Did you perhaps upgrade Internet Explorer recently? I had some problems after an IE upgrade, which required me to fix some scripts I had.
You could try removing all the scripts and then put them back one after another. Cumbersome process, but this may help finding the culprit script that breaks the compilation process (if any). To be sure, the problem is not necessarily in one of the script files. -- <http://forum.pspad.com/read.php?2,54807,54816> PSPad freeware editor http://www.pspad.com
