1156079 - [e10s] Plugin hang in UXTheme.dll with ProcessOrDeferMessage on the browser stack

Status: RESOLVED WORKSFORME

(Core :: DOM: Content Processes, defect)

Description

[Jim Mathies [:jimm]]

Win8 only, very common. There's slight variation in both stacks but the hang cause looks the same.

We hand these unknown system messages to DefWindowProc, which is probably a mistake.

todo: look at listing the value of the native message via annotations.
