Ended up debugging IE7 javascript last night and this link proved useful. The culprit in my case was a trailing comma in the last line of a jquery ajax post submission. My lesson learned? Use single line escapes for comments (//) rather than multi-line escapes (/.../), as it makes commenting out large sections of code considerably easier when/if you need to cut out sections for debugging purposes. A truly unpleasant reminder how awful it is to develop in IE, and how backward the browser is compared to Firefox from a developer's perspective.
