I think you are talking about the switchbar, right click in an empty area of that bar with the 'channel buttons' and select position > top, if you want it on top.
But even at the bottom it shouldn't overlap the taskbar, that could be explained by the fact that you have mIRC running in fullscreen, you can press F11 to toggle the fullscreen mode
