I'm using IDEA (atm 9.0.3) with ideavim plugin for about a year now, never had any problems.
But now, the editor hangs on about every word I enter (also with deactived ideavim).
I've tried reinstalling, didn't help, it was the same with or without my old settings imported.
So I tried using the project files from a colleague, with no succes neither.
I think it all started when I sent the project to a linux x86_64 machine and then substituted
my local project with a modified version that came from that machine.
