program runs differently on other computers

[tazboy]

I'm not sure if this is an AIR issue or Flex 3 issue. I have a program that works fine on my computer but when I have someone else put it on their computer it doesn't work the same way. Right now it's something as simple as a pop-up window not being able to be closed.

Has anyone else had issues like this?

Thanks.

You'd have to show us an example, with a small source code preferably.
