I'm watching this post very carefully.
I have also renamed every instance of the SuSEmenu.png that I can find and not having any luck in the lizard crawling away either.
I have no option to change that button in the appearance screen either, like some ppl obviously do on other distros. The button is fine and dandy, to start with, but common, this is Linux, thought we were 'open' about things like this!
Must be a config file somewhere that is setting this menu button up to act like this, should be changing that, not renaming icon files that might or could be used elswhere.
Bye for now <crossing fingers>
