Dup File

Hi there.Matbe you could help me . I've recently upgraded to PHPR 5.3 (Version 5.2.0.7113) from PHPR 5.1 (Version 5.1.0.2503).somewhere along the line I'm doing something stupid. I would create a project in 5.3 and bring it to a near completion when suddenly a error occurs and a PHPRunner7113.dmp file is created. From then on I could do what I want, I have to start all over. This normally happens when I start changing the Menu and table description in the MIsc tab, and in the menu on the Editor tab. Its actually driving me to drink !!. Any suggestions or help ? Thanks
