(FMP 4.0v1 W98/Me)

I start my FMP file.

I am in a layout, with window maximized.

I have a button on this layout directly linking to another layout (no script step).

This other layout is a list of records, each with a picture.

The first time I click this button, the second layout shrinks (as when you do a minimize script step). It takes a few seconds for my Model T Ford computer to load all these images.

But then, when later on I reuse the same button, the layout with all the records appears without shrinking, and quite fast.

Could someone explain, please?

I am wrong saying it is like a minimize script step: it is actualy that the main window splits in 2 (as when on a PC you click on the little double square icon on top right of all windows.

Any time a related file is opened, this behaviour can occur. The window is being 'restored'. Are your pictures from a related database that you are not opening when you first open the main file? If so, then there is your answer. And when you use this same button afterward, the related file is already open. Therefore, the main window is not restored. Try attaching this button to a script that opens the related database, goes to the desired layout, and maximizes the window.
