Visual Studio 2010 Debugger jumps around

Question

I have a simple C# Winforms application. It isn't multi-threaded (yet). When I debug it and step through the code at work, it debugs just as expected with the debug cursor moving line by line. But when I try doing this at my home computer, it behaves very erratic. The cursor will randomly jump to an unrelated line of code in the middle of another method that hasn't even been called yet etc.

The differences are: At work I use VS2010 Professional, at home I have VS2010 Ultimate At work, I use Win XP, at home I use Win 7 Ultimate At work, its a dual core Athlon, at home a quad core Phenom II
