Hi, I've worked the suggestions made wrt into that new patch. In particular, - subclassing is now properly done with SetWindowSubclass - uxtheme is delay-loaded - minor things like a correct "hot" flag and more cleanliness due the better subclassing.
I've uploaded the patch to: http://www.minet.uni-jena.de/~res/commctrl-themedbutton.diff [or would have ~32k been an okay size for the list?]
Reviews are appreciated.
