I have been running a trial of Resharper successfully but soon after installing dotCover 1.0 I have experienced two complete freezes of all Visual Studio menus. By "freeze" I mean that no Visual Studio menu will drop down even though at the same time the editing windows are alive and I can right click for a menu.
So far during my trial of dotCover I have only tested it via Resharper executing unit tests direct from a source code edit window.
I should confess that the concept of unit test sessions confuses me and I have not taken advantage of the test session "lock" feature. So maybe these VS menu freezes are because Resharper or dotCover is expecting me to complete something?
