Disable the blue highlighting for tabs?

BlitzPlus Forums/BlitzPlus Programming/Disable the blue highlighting for tabs?

The way tabs highlight in a dark blue color whenever I move over one is really annoying me... I was wondering if anyone knew how to disable this?

Also, I think I saw someone post some kind of code that would send messages to gadgets to make them do certain things that were normally not supported, and there were a bunch of constants with it, and I thought that might contain something to disable this for tabs.
