The version shouldn't be a problem - I tried it on both the stable version and 4.5.3 [2265], had no problems on either.
Duh! I'm so stupid - I just tried and it seems that on my Work computer the AppInit_DLLs key does not accept long filenames with spaces - with or without quotes. They did work fine on my home computer though - what's up with that? Try adjusting the registry value by putting the short filename (8.3 format) instead. I'm updating the readme file to reflect this now. For reference, your 8.3 path is probably: C:\PROGRA~1\PSPADE~2\PSPADS~1\PSPADS~1.DLL But you should check to make sure -- <http://forum.pspad.com/read.php?2,40832,40936> PSPad freeware editor http://www.pspad.com
