Don't know if this is a bug but here you go. I've a problem with the XM skin. In the screenshot you can see that if I press button 5 the selection is too big, parts of button 4 and 6 are also highlighted. I double-checked my ini file. That doesn't mean I'm sure thats a bug. But in the standart skin is the "rotating" xm-logo at this position. Is this a predefined area ? At least I think this is the cause of the problem.
Attached are a screenshot and the xm.ini
