Hi: I have started this problem quite often now. I am using 6600 to test one of my appln, it was behaving normal for the past few days but now suddenly it has started giving LCDUI exception quite often; exception comes when display is Xfered to another displayable object. Place of exception is also not fixed in the appln. SOmetimes it throws exception and appln crashes and sometimes it works fine. Is it a firmware pblm, there is nothing wrong in the code. PS: Appln was running quite smoothly for the past few days.
