There's nothing intrinsically wrong with the topic of this thread. GUI customizing really started with this sort of 'adventurous' modification of code.
I've used 16 bit and 32 bit resource hackers in the past....but then I've also taken full responsibility for my actions, knowing full-well that if and when things go pear-shaped I'm stuck with getting myself out of my mess.

The caveat is, as with alpha and beta proggy use.....enter at your own risk.
Generally it is considered a violation of the EULA as it is reverse-engineering to open a dll or exe file [modified or not]....
