Comment (by stuartm):

 There's no entirely correct and complete fix for this which could be ready
 for 0.24 and I'm loathe to add specific hacks.

 The main part of fix would be not to rebuild the entire list each time,
 that's extremely inefficient and we've already moved away from that in
 other places. We need to add the following new events
 SCHEDULE_ADDED_PROGRAMS, SCHEDULE_DELETED_PROGRAMS and
 SCHEDULE_UPDATED_PROGRAMS which permit incremental changes to the list
 without starting from scratch. This would greatly improve UI response too.

 We also need a generic method in MythUIButtonList of remembering
 positions, something that works equally well for all list layouts,
 selection and wrap styles. This much might be possibly achieved for 0.24
 and would mitigate the problem, though probably not eliminate it.
