Alex.
I am the kind of guy that is happy to solve a problem without understanding it.
But this one is, er, bugging me.

Subject: Re: Counting problem
I see the same problem on both 5.5.3 and 6.0.1 - but testing in the
message box.
Oddly, I happened to notice that if I change the script to be
put "a,b,c,d,e,f,g,h,i,j" into temp
repeat 10
add 1 to counter[any item of temp]
put counter["b"] into tJunk -- i.e. I add a single useless line
!!
end repeat
it works just fine every time.
Don't know if that helps you or makes it worse :-)
