Well, it is probably just hiding as a result of being scared from the crash. Happens to me too.
However . . . this is what I do
#1 - Open Text editor, or the Menu Function under question: FX, TextGen; Pan/Crop . .Track Motion . .
#2 - Gently roll cursor over the bottom edge of that Menu, the cursor turns to a double headed Windows Re-size Icon thingy.
#3 - Hold down ( left or right . .not sure which??) mouse button and drag vertically and re-open Keyframe timeline.
Get back and say if it worked?
