My work laptop came with DOS and Windows 3.1. I bought OS/2 Warp for the pre-emptive multi-tasking I was used to on my Amiga. I was building a dBase IV app using two DOS windows. One day while I was compiling my app in one of the DOS windows, the WorkPlace Shell crashed. After a minute the DOS windows went away and a few minutes later they came back along with the WorkPlace Shell. My app was still compiling. I was impressed.
