Hi Mark,
I recently updated to 2020.16.20.100 (Professional). I noticed that when the Fund Manager window is maximized it works as expected. When I switch the window to anything smaller by clicking the double square icon to the left of the x in the windows bar, I notice that the windows I have open within Fund Manager do not automatically resize and there are no horizontal or vertical scroll bars. Honestly, I cannot remember exactly how it worked before but I remember the navigation was easier
