After opening a PHP file and reading it for some seconds, I got an error message, that PSPad is not working anymore, and a button to close the program. There was no access violation showing up. This happened occasionally also in previous versions. I had some other files opened. PSPad was running since three days, so since I updated to 600 I did not close it, and there were no other issues.
