Channels In Use Tab Doesn't Behave Properly with many Mulitcells Patched

Hi,

The channels in use tab doesn't behave as expected when a large number of cells are patched. When a channel number is selected on the command line past a series of multicellular fixtures, the display doesn't move to look at that channel I believe it is not counting the cells row when it is deciding how much of the list to move past to see the selected channel. It also doesn't seem that the cells off Flexi option works on this tab even though other Flexi modes do.

Also on Mac when looking at this tab and scrolling it appears to consume a lot of computer resources for some reason.

Thanks!
