You're kidding, right? You really don't see the hole in your "if (TimeTks ==
TimGetTicks())" logic below?

If a system action stops the app from executing for some period of time during your
while loop (e.g. interrupts become disabled, background thread suspends app thread,
tick counter gets reset, etc.) it may never exit the loop. The correct test is "if
(TimeTks < TimGetTicks())" and use a UInt32 for the TimeTks variable. You should also
test for overflow in your initialization of TimeTks, though the only thing that would
happen if TimGetTicks() + 110 overflowed a UInt32 is that the splash screen would go
away immediately.
BTW, this approach may annoy your users, because they can't tap the screen or press a
button to dismiss the splash screen. It's not at all Zen-of-Palm...
