Send mouseUp doesn't work in Windows standalone

[Bill Vlahos]

I have the following handler in the Stack Script:

on openStack
   resetOpen -- prep the stack handler
   send "mouseUp" to button "Server Data"
end openStack

It works correctly on Mac OS X builds but doesn't do anything on 
Windows standalones. Clicking on the "Server Data" button works 
correctly on both platforms.

Built with Rev 2.1 on OS X. Any ideas why this doesn't work?
