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;
                DispatchMessage(&msg);
        }
        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:
http://www.crash-server.com:8080/public/tsvn/71040F62-F78A-4953-B5B3-5C148349FED7/symsrv

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 :(
