Re: Branch/Tag dialog hangs when closed with ENTER

I did some further testing and I have to mention that most of my
initial hints were wrong:

- It may also happen when clicking OK with the mouse, and it does not
always happen when pressing ENTER. (But it happens most of the time.)
- There is no connection to the restart of explorer.exe

Further observations:
- while the dialog is hanging, sometimes you can move the window with
the mouse, sometimes not
- also while it is hanging: sometimes its content is redrawn,
sometimes not
- the process does not eat any cpu while it is hanging, there is no
disk io, and there are no context switches.

While the TortoiseProc.exe process is hanging, it contains 2 to 4
threads (it looks as if the longer it is hanging the fewer there are).
I've attached the call stacks of the remaining two threads as reported
by ProcessExplorer.

Interference with other shell extension: I deinstalled TortoiseCVS and
rebooted my computer. It didn't help.
