OK, I think that I've narrowed it down. A readonly edit control sends a WM_CTLCOLORSTATIC message before re-drawing, rather than a WM_CTLCOLOREDIT message. In the former case the code sets the background mode to TRANSPARENT, which I think it should not be doing for an edit control - just not sure what the right change to fix it is :-) I have also turned up an issue with the -noflicker option, where the text completely disappears (try adding -noflicker => 1 to the window creation of your script below). I suspect this is related. I have raised 2 trackers for these issues: https://sourceforge.net/tracker/index.php?func=detail&aid=1246429&group_id=16572&atid=116572 https://sourceforge.net/tracker/index.php?func=detail&aid=1246431&group_id=16572&atid=116572 Rob.
