I am getting lots of memory problems in my app under vista & windows xp

the message is"Visual dBASE may have become unstable, Do you want to attempt to save your unfinished work before exiting ? If you choose Yes , you should exit immediately afetr saving your data . choose No to exit now"

This message is coming up more & more every time the ap is opened

The user can simply answer No & go back to the desktop & re- open the app. But within 3-4 mins the error keeps cropping up
