I’ve had problems debugging since I installed VS2008 SP1. When I hit F10/F11, the debugger sometimes changes this to a go command and continue to run the rest of the code. I’ve been looking for a solution for this problem without any luck. So I was very pleased when someone on my project team came up with a link to a Microsoft hotfix yesterday :-)

You can download the hotfix “Updates for Visual Studio 2008 SP1 debugging and breakpoints” here:
