My problem is my bathroom windows. The picture I send is from another room but have the same kind of window pic 342. First, pic 341... the screw is missing from the bathroom window and the two cut out space next to the screw. I see a piece of metal cracked. Pic 343, the plastic piece seem to be the problem is stuck and making the window very hard to open and shut. Is there a way to fix this problem or I have to replace the window.
