i installed windowsFX. In the config. options, there is a feature to Maximize to size.

In here, you can effect the size of window when holding down shift or control & selecting the resize icon in top right corner of window. But niether of theese options are working.

Ive tryd reinstalling but it didnt help. Is it possible that Windows, or another application, is using this funtion. or is it somthing else like a windows update issue???
