When you see access violation thingy, go back to Delphi IDE (without terminating your app), click on the Search menu, and choose Find Error.

Enter the address with the error, and Delphi will attempt to locate the line number for you.

You should also check out Madshi's nice components at www.madshi.net, it has a nice exception handler package (madExcept)... 'nuff said :)

jclDebug is also excellent for this type of problems, and provides stack dumping (=>> call list before the "crash"), etc.

www.delphi-jedi.org if i remember
it's freeware
