Did you report this bug to the IE team?

  I'll ask Stuart (the author)
  - reybango 14y ago
    Could you ask Stuart to email me a test case so I can look at it? We tried looking for a way to get a hold of him but couldn't find any short of a general email address on the company site. reybango at microsoft [dot] com

  They'll just tell him that he should fix his CSS (https://groups.google.com/forum/?fromgroups#!topic/microsoft.public.internetexplorer.general/gKJkXcWYpLI https://groups.google.com/forum/?fromgroups#!topic/microsoft...). The only thing publicly announcing a MSIE bug will do is subject the author to ceaseless attacks from "you're either with us or against us" Internet Explorer fans (speaking from personal experience.)

    2013 Microsoft seems to be trying hard not to be 2009 Microsoft. Might be worth another shot.

      I'd say "2013 Microsoft is trying hard to seem not to be 2009 Microsoft." Same words, but what a difference!

        I've taken a second look at some MS products in the last couple of years. There's tangible improvement, to the point where I don't use what I used before in some cases. I switched to Bing from Google, and switched to Live Office (the free edition) from Google Docs. Google only wins in accessibility--I can reach everything easily from one place. That's where MS has a lot of room for improvement. I would consider paying the $5/month for Office 365 if Google ever took away my free domain email hosting.

    I don't see any MS employees answering there. Or don't they say so when answering on the newsgroups?

    sorry but your company's browsers have caused many web devs to spend hours making their work look correctly in various IEs. Nowadays there are frameworks like HTML5 boilerplate that help us along, but not so long ago it was extremely painful. Worse are MS email clients even the most recent one which uses the MS Word engine to render html emails. Further, if you want to create an innovative web app for mobile and desktop there is a ton more effort and work that needs to go in it if you want to reach the IE audience. It may not even work at all even after trying to get it to work - uggh!

    "While it would be nice for IE to not get stuck like this, it would be much better for HTML authors to take a little more time and not put badly formatted junk into their sites." Wow. Just... wow.

  I've ran into this bug before with a dotted border along with a border-radius on an element. This bugged the hell out of me and I was in contact with a friend from the IE team who was also debugging it. Finally isolated it to a small piece of code http://pastebin.com/w7YGvgWs http://pastebin.com/w7YGvgWs Apparently this is actually a browser hang and not actually a crash. The friend reported it internally, but he said they probably wouldn't actually fix it in IE9 since it wasn't a crash and wasn't exploitable. So, yes, the IE team is fully aware of this bug.

Of your fixes, did you need to do all of them or was any one on its own suffice to fix the problem?

Would be useful if there's a simple testcase page for this.

The text doesn't mention if the bug remains in Internet Explorer 10. It would be interesting to know if the bug has been fixed in the latest major version. Does Microsoft send out non-security updates for Internet Explorer 9 for those who are unable or unwilling to update to the latest version?

    That code won't kill it, it seems to need a width and height, see this one: http://codepen.io/beeglebug/pen/ntLbv http://codepen.io/beeglebug/pen/ntLbv

      Doesn't kill IE10 on my box. V: 10.0.9200.16521

        Microsoft should claim "We don't have Something like bugZilla". OR We are unable to reproduce the bugs you have claim.

        Hello hp50g, Thanks for your link I have used http://webmatrix.uservoice.com/ http://webmatrix.uservoice.com/ too much. Search for google on this site with "Kristina". You found a lot of post written by me. I just hate it because I can't gave it to fellow guys work on Linux and Mac. Secondly When I tried it it's crash too much. I write a lot of post their but atleast finally move to Sublime text 2.

Hopefully, Microsoft will get around to pushing IE10 to consumers soon. IE10's market shares stands at 2.35%. http://gs.statcounter.com/#browser_version-ww-daily-20130218-20130319 http://gs.statcounter.com/#browser_version-ww-daily-20130218... I look forward to it hitting double digits this year.

ooooh I have a story similar to this Back in 2010 I moved to a new city, and was trying to find a graphic design firm that wanted an in-house web developer. I shopped a resume (with prominent link to on-line portfolio) to all sorts of shops, never got a single call back. A while later, I had brief access to a Mac, and decided to check out my site there (those were the dark OS 9 days when Mac testing was sort of optional). Turns out that a CSS glitch in IE Mac would take down — not just the browser — but the entire computer. I had been walking around crashing systems and losing peoples work for months.

  I don't think you meant 2010 there...
