Workaround: don't try to close the DOS box. When you need to close DOS
shell session, type "exit" and hit Enter.

This problem require windows executable bzrw.exe. It's not ready to use yet.

I can reproduce this on XP Pro without using bzrw.exe.

1. Start bzr explorer using shortcut from standard installer (in my case bzr-2.0.0rc2-4-setup.exe)
2. Select Tools, Advanced Commands
3. Try to close the command prompt window using X in title bar
4. Press Cancel in the End Program dialog
5. Select Tools, Advanced Commands

And watch the error messages fly!

Perhaps, you misread. bzrw.exe should be cure, not catalyst for the problem.

As I already wrote: don't close DOS box please to avoid this problem.

Yes "This problem require windows executable bzrw.exe." means bzrw.exe
causes the problem. It would have been clearer if you'd put "To fix this
problem requires bzrw.exe" or something similar.

Personally I would never try to close a command prompt while it is
running a program but some may try to do so.

Oh, yes. Sorry for my bad English.

Believe me... This is how windows users expect apps to behave. The
fact that the problem does not occur immediately after the sin is
committed makes this a problematic known issue. Looking forward to
bzrw.

Martitza, believe me: I know. I am windows user too.
The best we can do right now in bzr-explorer is to disable Tools -> Advanced because it creates too
much problem.

[Martitza (martitzam)]

I think that is resonable. Incompleteness creates a better impression
than a hanging app. Everyone knows explore is a long term vision.

In bzr-explorer 0.10 there is qrun command invoked instead of shell session. It should work better now.
