Flash crashing IE7 on Windows XP
The PC Team worked on a problem this past weekend with our partners at the LRC. The LRC was reporting that an online exam was crashing IE7. The exam is a custom web app developed by the Med School, and it was completely closing the browser without generating an error message. We began by running their web app on our own machines, which we had set to display more verbose error messages than the lab machines do by default. This revealed a few bugs in the app's JavaScript, but did not seem to fully explain what we were seeing. Further investigation by ourselves and the LRC staff revealed that the app was closing most often at a particular point where the web app used Flash. We also found out that the LRC staff had noticed problems recently with other apps that used Flash. A short Google later we had found that many people are seeing similar problems with Flash 9 crashing IE 7. Our labs are currently using IE 7.0.5730.11 and Flash 9.0.47.0.
The IT folks at LRC were able to make some changes that increased the stability of their web app, and will be further testing to find out how compatible their apps are with current versions of Flash.
