I don't know how to explain you that application doesn't create "preview" for OS. OS creates preview from application. It's the same as you ask web page developer to make his web updated in browser tab preview.
I will try to look if there isn't any possibility to force OS create new snapshot. Anyway, it's possible it disappear after I will move PSPad to new Delphi version. But then more power I will put into fixing things like this one, then longer it will take. -- <http://forum.pspad.com/read.php?2,66718,66807> PSPad freeware editor http://www.pspad.com
