Hello,
I would appreciate any advice about removing an insect net for cleaning. It is in an apartment, and the outside of the window cannot be accessed.
The window has a winding mechanism for opening. I can find 3 screws around the window - 2 holding the window winder in place and 1 retaining clip at the top of the insect screen. I removed all 3 screws but can't work out how to get the insect net off.

There is a small lip at the bottom edge of the window holding the insect net in place. With the window open, I have tried pushing the bottom of the insect net away from me and pulling the top towards me. However the middle section of the insect net frame can only move about 1cm when I do this. The left and right edges of the insect net frame feel very stuck. I have tried pushing the frame of the insect net in different directions in case there is a spring mechanism or a catch, but I cannot feel any give when I do this.
Any advice appreciated!
