I have a basic script to display a layout with a related record.

Currently i have the existing window used to display the related record. Then the use clicks on a button to navigate back to the original layout.

However, i want to change this to display the related record only in a new window instead, then simply close the new window when done, and therefore be back at the original layout again.

I change the GTRR script by selecting New Window.

But for some reason the original layout, which i have set to Maximised, changes size to a smaller window next to the new window.

How can i simply have the new window displayed on top of the existing window, without the existing window moving/resizing?

Unfortunately,maximizing a window maximizes them all, and restoring/resizing a window returns all the windows to their set size. You could set the window you want to maximize to a size that appears maximized, though.
