I see an earlier message about oversized popup windows, and the inability of closing them. Looks lilke the same thing to me, although it was supposedly fixed in 1.6.0
I look around for any logs and send them to support.
Hi I haven't received any logs files you need to send the jaikozdebug-0-0.log and jaikozuser0-0.log to support at jthink dot net. Yes a problem with oversized dialogs was fixed, could you also do a screen grab as i havent been able to reproduce your problem.
