I also get the same strange overlayed characters in the logwindow. It occurs the 2nd or 3rd time I try to compile (mingw C++). After restarting PSPad it works for 1 or 2 times and then the same happens again.
I'm using Windows Vista Ultimate English (but location settings on The Netherlands aswell), UAC turned on, on a dual core CPU. PSPad 4.5.2 (2241). -- <http://forum.pspad.com/read.php?4,37697,39246> PSPad freeware editor http://www.pspad.com
