Is there a way to set the screen size and position of a window upon opening? By position, I mean position in relation to the screen itself. Thanks.

FMP has no direct control over the *screen* size and position -- that's under the user's control and is a function of the operating system. You do have control over the *window* size.

FMP lets you check what the screen size and colour settings are with the Status(CurrentScreenHeight), Status(CurrentScreenWidth), Status(CurrentScreendepth) functions. You cannot change them directly from FMP, but you could write a screen changing thingy in Winbatch or AppleScript and call it from within FMP to perform a screen settings change.

On PCs, I don't think the developer has control over the main FMP application window -- that's under user control. You could perhaps set up a shortcut that controls whether the application window is maximised or restored I guess. (This is not an issue with MacOS.)

The developer *does* have control over FMP's file windows via the "Toggle Window []" script step -- it can be set to minimize, maximize, zoom and restore (hide, zoom, unzoom and maximize on MacOS).

On PCs I prefer to have them all maximised all the time, and switch between them with the "Refresh Window [bring to front]" script step -- shuffling the windows like a deck of cards.

Sorry, I did mean "window", not "screen." I'm using the toggle function, but I still would like to know if there's a way to set the position of the window on one's screen. This shouldn't be too difficult, if FMP's included the capability. All I would need is Status(CurrentScreenSize)
