It is probably related to the patch which was to fix InnerSpace "disconnecting" from the game.
As most users don't have their ISBoxer window layouts set as fixed, no border, then they don't have any minimize/maximize buttons to press in the first place. The other possibility is you have no window layout at all, which is also in the small minority bucket.
It will be added to the to be looked at list.
You could revert to the
older 6294 release build, but then you will potentially have issues fixed in the later dev builds if you had them, like WoW 3d acceleration error, or Inner Space disconnecting in certain areas.
