From 6.17 versions.txt:

79. Fixed switchbar button text color not matching XP theme color.

I am not sure which theme text this is supposed to match, but it does not appear to be button or dialog text. All I get is black, which is unreadable with a dark windows theme.

In my opinion, the best solution to this is to allow for a separate color setting. It seems like it would have been an easier and more functional addition. I am not giving up dark themes just for mIRC. :tongue:
