The size can't change because of space limitations. I could make it flash, but then what when they forget again? Add a sound to remind them? Then make a pop-up dialog every 10 minutes to remind them?
This would not be an issue if Microsoft would do to their scripting engine what Mozilla and Google have done. They're currently playing catch-up but at least they are working on it, so we could potentially get there soon.
Ultimately what is on the to-do list, to complete as soon as the scripting engine makes it feasible, is a background save mechanism. Still enabled by preference, but once enabled it would make saves of the tournament to temporary files automatically. This would allow crash-recovery.
