VS2010 takes long time to show a project properties

I have Visual Studio 2010 Ultimate installed on my super machine (8 Xeon Processors, 12GB Ram, ...). My problem is that VS开发者_如何学Go2010 takes a long time to open any project properties!!

Does any one knows a fix to this problem?!

Thanks in advance.

I found the solution!! You just need to delete the solution *.suo files, it seems they got corrupt!! After I did that everything returned to normal again, even the solution build process is now several times faster!! :D
