5.0.2 startup woes

[Fred Moyer]

Now with this new 5.0.2 that I just purchased, various startup, openstack and preopenstack commands do not implement -- that is they don't implement when I double-click on the stack while LiveCode is not running. (Everything works fine if LiveCode is already running.) But, for example, if you make a stack that simply consists of a stack script that says:

on openstack
  choose browse tool
  beep
end openstack

If you double-click on the stack with LiveCode not running, and 5.0.2 starts up, does the tool change to browse tool? In my computer (Mac), it doesn't -- but the computer does beep. Am I missing something really basic here? If I drag my new version 5.0.2 to the trash,  which leaves 4.6.4 to start up, and do the same thing, the tool switches to browse tool as it should. There are other startup issues suddenly going on in 5.0.2 which I don't understand.

Can anyone advise?

Thanks
Fred
