Waiting for the train

[Richmond]

I have a stack that sits around as a Palette with a script in it that
repeats itself every 18000 ticks (that's 5 minutes to Thee and Me) with
a code like this:

*put 1 into KOUNT**
**repeat until KOUNT = 1003*
/do various jolly things/
*add 1 to KOUNT**
**wait 18000 ticks**
**end repeat*

The "wait 18000 ticks" seems to be locking up the whole IDE so I cannot
get on and do other things . . .

Would be grateful if anyone could suggest a way round this.

Richmond.
