I “improved” my script just to check that each time the handler is called it still gets its own local variables:
on oneOrTwo local tCount add 1 to tCount put "one" && tCount & return after Field "Field" wait 50 with messages put "two" && tCount & return after Field "Field" end oneOrTwo As you would expect, if you make tCount script local rather than handler local, it is “shared” between the “pseudo-simultaneously” running handlers.
