Wait with messages

[camm29 at tesco.net]

I have a loop with :-

repeat
..... do something (takes about 250ms)
wait 1 millisecond with messages
if x=1 then exit repeat
..... do something (takes about 250ms)
wait 1 millisecond with messages
if x=1 then exit repeat
end repeat

I have a button that makes x =1 to exit 1 card and go to another

The seems to be a larger delay than i expected to exit the repeat 2-5 secs ????

Any ideas how to exit repeat very fast ???

Thanks in advance !
