An error is thrown if there are 2 or more tracks listed in the 'Track List' and then clicking 'Select All'. This error is only thrown when 'Select All' is first clicked. After the first click BG & FG can be changed or no change at all and clicking 'Select All' causes no additional error.

NOTE: this error seems to only get thrown IF the multiple selected tracks are set to '1 track' - there is no problem if they are set to '2-track'
