During the last days, I got a lot of trouble with my Visual Studio 2008 Prof. Each time, when I want to reorganize the toolbox for the WinForms-Designer, Visual Studio 2008 crashes completely without an error-message.
I tried it a couple of times, without any success - damn. I tried the same on an other computer - nothing happened, just the normal behavior - Visual Studio opened the dialog-box. Later, I ask Google for a solution - well done. I found a post in a newsgroup with the same background.
The reason in my case was, that I have had installed the "Power Commands"-AddIn. So, the solution was quiet simple - just uninstalling the AddIn and try it again - with success.
