Several times today RS have been locking vstudio and I have to kill it due to it uses some modal dialog that won't disappear. It seems to happen now and then when a window is loading and I want to abort operation (chose incorrect command) by clicking Esc, then RS does not seem to handle it gracefully and vstudio UI is locked.
Here I for some reason opened ".NET Tools Extensions" when really wanting opening options so I hit Esc before window was completed loading, and I get some weird "Close?" dialog every time I try to Close it via "Close" button. Need to kill vstudio process again.
(Also settings does not seem to be migraded properly from RS 7.1, a lot of stuff needs to be re-set)
