I'm really sorry for not replying, satch.
Thanks for posting, armando

Satch: the problem with your grid's 15th and 16th hotspots is simple: it's the variables. In TriggerRight, there's a variable named "monitor2witdth".
This causes GridMove to ignore the hotspots. Yeah, there should be some time of warning, but this is used to prevent the hotspots from being drawn when there isn't a second (or third, etc) monitor.
About Chrome.. I haven't been able to fix that problem because apparently that problem has been fixing itself!
I've tried to debug it, but both times I talked to the users having the problem, it just stopped happening without anyone doing anything!
