EASY to reproduce to the point where the program GPFs. Open up any file, or even the default blank new single tabbed window. Go to _Window_>_Horizontal Split_ or _Vertical Split_ Right-Click on the tab with the horizontal split, select _CLOSE_.
Result, spectacular crash. :] After that, the program pretty much becomes useless until you close it. Which results in a few more GPF errors. The version I'm using is 4.5.3 (2298) -- <http://forum.pspad.com/read.php?4,52021,52021> PSPad freeware editor http://www.pspad.com
