Something strange happen to my TG50 lately
When I am trying to ran some applications like qoffice / documents to go / tpunes or any other "heavy" application I got two kinds of stacks:
1. White screen and the TG50 stop responding - only reset helps
2. Some king of Error , like below
MemoryMgr.c,Line:3583 Free Handle
Another time when it got FATAL EXCEPTION is when I browse the internal memory , with any file manager except of 3XCom.
On many occasions there is hard reset (loose of memory) , but then I just restore from the mspro
I had a similar problem with my TG50 about a year ago. Sony did not seem to know what was the problem even after I sent it to them. I never did get it to work. It looks like it might be time for you to upgrade (or just get another TG50)
