today I encountered a very strange problem:
I have two projects with same Ruby 1.8.7 SDK and nearly the same gems (on MS Vista 64)
When I run the tests in project one, Ruby freezes after some tests run successful (it freezes at the same test every time - it seems to be the last unit test, so maybe it freezes on the switch to functional tests)
I have to go to the task manager and kill it.
Same tests work fine under "cmd" (with "rake test").
The tests of my second project are working fine under RubyMine.
Do you have any idea, where to search for a solution?
