Betreff: AW: AW: Commit dialogue freezes sometimes on Win10

It loops forever in the PeekMessage() loop within this piece of code:

// COleMessageFilter standard implementation of callbacks

BOOL COleMessageFilter::OnMessagePending(const MSG* /*pMsg*/)
	// By default we rely on OLE's default message handling for every message
	//  except WM_PAINT messages.  WM_PAINT messages should not generate
	//  out-going calls.

	BOOL bEatMessage = FALSE;
	MSG msg;
	while (::PeekMessage(&msg, NULL, WM_PAINT, WM_PAINT, PM_REMOVE|PM_NOYIELD))
		bEatMessage = TRUE;
	return bEatMessage;

As one would expect, the contents of msg is always the same = WM_PAINT, but with a different
time field, so Windows seems to continue to generate WM_PAINTs for some reason. I tried manually
setting the EIP to the "return bEatMessage;" statement, hit "continue execution" and that
seemed to do the trick. The UI is responsive again, and subsequent calls of that method (I
left a breakpoint at the entrance) no longer get stuck.

Here's the stack, just tell me when you need sth. else:

I'm sure you know your way around a debugger, so you could attach a 
debugger to the TortoiseProc.exe process and find out where/why it hangs.
The debug symbols can be set up with this url:

And if you have the debugger set up right, it will also automatically 
check out the TSVN source files if necessary.

I haven't seen that problem on my machines yet, so I can't really help 
in narrowing the problem down :(
