Hi Tihomir,
Yes, I think I am using the latest deisgner 2.2 code.
I did try google chorme frame, with google chrome frame, the only version of designer worked was jBPM 5.0-CR1 release, after that I have tried 5.1, 5.2 and now the latest, none of them works on IE. I heard Signavio has made it work on IE, at least on their website they say so, but did not have a chance to try it yet, maybe that is a good sign for IE :) .
Thanks again for the quick response.
