Hmm.. I'm wondering if setInterval() and setTimeout() can be used as I expected. I was thinking I could use those to have a function be called while my script is doing other things. Say, for example, in SlyEdit, if I wanted it to udpate the time in the corner of the screen at a regular interval, I was thinking I could use setInterval() to have it run a function to do that at a regular interval (while the user is still editing a message). But with the behavior you describe, I'm not sure if that would be possible?
