Hi Daniel,

I've experimented the same problems using the installer for mono 1.1.7.
The problem is that Win32 installer for mono-1.1.7 comes with a gtk#
1.0, version 1.0.9. The bug your are experimenting is solved at 1.0.10
release which seems to be released inside Win32 installer for Mono
1.1.8.

I can't confirm you if Mono 1.1.8 installer solves the problem. What we
have done to workaround this problem is to use Mono-1.1.7 win32
installer and to install over it gtk# 1.0 (version 1.0.10).

You can check the following thread for more information.

I hope it helps Daniel,

Cheers.
