Running Visual Studio Professional 2010 with Unity Pro 3.4 - when I alt-tab back and forth, eventually Unity crashes on receiving focus. Size of the project doesn’t seem to matter - it happens even when working on small tutorial/test projects (eg. a few primitives, 4-5 small scripts) - is this a problem with my setup? Or a problem with Unity 3.4? I don’t recall having the problem with earlier versions of Unity, but I never used it as much as I am now either, so can’t say for sure.
