I have a strange issues with the latest builds of ReSharper 5.x. First of all my evironment:
Windows XP Pro x64
Visual Studio 2008 Professional Edition
Sometimes, when I run a Console Application (with just a Console.ReadKey()), it launches, but the console window does not appear. Furthermore I cannot hit the break button in the Visual Studio IDE because it is unresponsive as if a model dialog is open. When I look in the Task Manager, I see that the Visual Studio IDE is responsive. I then have to end the devenv.exe process.
I don't have this issue with ReSharper 4.5.x
