i'm working on a Visual Basic project. After installing Build 1170 the Editor hangs very often. The UI dosen't respond anymore. There is no activity for Visual Studio in the process explorer. I can only kill the Visual Studio instance. I guess the problem is related to the Intellisense functionality because the hangup occurs just before the intellisense pops up. Very strange is, that i can't use my Firefox bookmarks while Visual Studio hangs.
As the hangup occurs every several minutes i deinstalled 1170 and returned to build 1168 which was quite stable for me.
