g'dae,

  This may appear as trivia to some, but I would dearly love to hear from
anyone who *knows* the answers to any of the below.  I have made my 
(un)educated guesses, and would like them confirmed.
  
(1)    What is the behaviour of the function "TickCount" 
       (alias the Global "Ticks") when at the limit of its range?  

(2)    Am I correct in assuming that this limit is 2^31  - 1?

(3)    Does it rollover to 0?

(4)    Does the System behave correctly when the rollover occurs?

  According to my assumptions above, this should occur once every 13 odd 
months for a constantly running Mac.  
  
  C'mon folks, stop chuckling, I'm serious.  I intend to use this info.

Thankyou,

Paul Menon.
