291247 - Browser thinks you are still dragging even though it lost capture in an annoying special case

Status: RESOLVED EXPIRED

(Core :: Widget: Win32, defect)

Description

[pete]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b2) Gecko/20050327 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b2) Gecko/20050327 Firefox/1.0+

1. Open the browser and some other program (has issues with notepad and winamp,
so try explorer or AIM instead).
2. Either resize a frame, select text, etc. in mozilla
3. While the mouse is captured, alt+tab to the other window and release the
mouse in the other program's window.
4. This part here is situational whether or not you can alt+tab back to mozilla.
It seems in an embedded window like a text edit control or inside a [i]frame,
you can, but otherwise it will cancel the event and appear to work correctly.
The safest way to reproduce this is to make the other window always on top and
still make the mozilla window visible, alt+tab to it, release the mouse in that
window and the move the mouse over to the mozilla window.
5. Mozilla still thinks the mouse is captured and the button is still down.

See WM_CANCELMODE and WM_CAPTURECHANGED under MSDN. Both messages need to be
handled for this to work in all cases... Well almost all, it wont work if you
break into a debugger while the mouse is captured.
