I have yet another minor problem with my program...

I have 2 screens swapping between each other for the title
sequence of a program.  I want these screens to swap about every
5 seconds.  I am using Delay() to do the timing for the screen
swapping.  However, I want the user to be able to click on the
mouse button to end this intro sequence and load the main program.
The problem is Delay() will not return for, at worse, just under 5
seconds, which is too long.  I would like to be able to detect the
mouse press straight away, and still have the program swap 
screens correctly no matter how fast the machine it is running on
is.  I am an old Z80 assembler programmer and my mind is screaming
interupts as the solution to this problem, but I have no idea how
to set one up on the Amiga to do this.  Examples/references/other
solutions would be appreciated.  

Wait! I have another idea!  How about using WaitTOF!  After
each of these I could check the mouse event and increment the timer...
Sound ok?

Thanks,
