When I launch my solution in FM16, the window is maximizing. This doesn't happen in FM15 and I can't see anything in my opening scripts that would cause the window to maximize. Any ideas?

Typically if file was opened locally and the window size and position was set. Once you host it that window size and position I believe is remembered. If  you turn off the On First Window Open trigger and it still does then it's not in your script.

 

Thanks for the reply and sorry for the late acknowledgement. I checked your suggestion but that didn't seem to be it. I had some maximize script steps to compensate for how pop-ups open in Windows. Now that behavior mimics the Mac OS. I do seem to notice it maximizing in some other instances, too.
