Prepar3d 3 with Reshade 3

Hi

When I open reshade in game by Shift+F2 the reshade window shows, but when I try to use the mouse and click to select a button or do anything else with the mouse in the reshade window, it doesn't do anything in reshade - the clicks are recognized normally by the game. So when I click on the reshade window the normal game mouse click is recognized. I cannot do anything with reshade with this problem, or I don't know how can I do it without working mouse click.

Thanks for your work.
