Usually after hitting preview few times (Preview mode set to HTTP) i'm unable to lunch my games. IE9 shows only white screen, looks like something is loading but nothing is changing. Have to force it to close by shuting down IE process in task manager and after that when I want to restart C2, the project is closing but C2 stays open and can't be closed - again task manager helps with that.
Using File in preview mode works everytime.
This was fixed a while ago, I had no issues with previewing in IE9, but it looks like ugly monsters have come back again.
win 7 64bit IE9
