Editor problem with shoulda test file

Hi,
I installed RM 3.1 EAP. When I editing shoulda test file I notice some issues with editor. It seems like editor can't follow with my keyboard typing. Example when I try to type "respond" in editor I get "rsn". I turn off the autopopup completion but this didn't help me. I am sure my keyboard is in fine state. I use Mac OSX version of EAP build.
