We need a sampling of the browser-side matching stacks for these signatures. I suspect that SetWindowPos is dispatching synchronous windows messages, but I don't know whether this is deadlocking with the browser windows or with the Flash windows.

It's #2 Flash hanger after bug 789379.

Comment 3

[Scoobidiver (away)]

It's #17 Flash crasher in 11.7.700.224.

Comment 4

[Benjamin Smedberg]

I'm closing a lot of bugs which are filed as Adobe Flash bugs which are either irrelevant, not actionable, or not serious enough to track in the Mozilla bug tracker. For the most part, Flash bugs should be filed in Adobe bugbase, and we'll only track a few highly-critical issues in the Mozilla tracker.

Version and milestone values are being reset to defaults as part of product refactoring.
