This was a tough bug to pin down, but it is a bug in LC901 through 
905rc1 and perhaps earlier with the moveStack handler not always 
redrawing a stack whose position is adjusted by the handler under OSX 
(tested on El Capitan and High Sierra)

Test stack and recipe reproducing the problem posted to the Quality 
Center bug: https://quality.livecode.com/show_bug.cgi?id=22267
