Axiom Pro 49 with Pro Tools - Bank up/down loses track of tracks ? Bug ?
Windows XP SP2, Pro Tools M-Powered 8.0

Normally, the Track up/down (F2/F3) buttons move the track selection (in Edit window) up and down, and the Bank up/down (F6/F7) buttons move the selected 'group of 8 tracks of interest' up and down.

However, I find that if not all tracks are visible (some are hidden in the Pro Tools 'Track List' window), then after adjusting Bank up/down all the way to the bottom, then try to go back up, it forever refuses to go all the way back up to the first 'group of 8 tracks of interest'. At this point, even Track up/down refuses to move the track selection up into that group of 8.

This could be a Pro Tools bug, or an Axiom bug. Exiting and restarting Pro Tools bring it back to sanity. Also, in my limited testing, as long as I have all tracks visible, this problem does not manifest.

Anyone else see this problem ?
