Ok, here's the deal. My living room window is Milguard brand. A center window with 2 smaller sliders on either side.




They are double-pane and sealed. The one on the right appears to have had it's seal broken because there is now a sheen on the inside.

My question to you all is if there is a way to replace the smaller slider window without having to do the whole 3-window affair? I've studied and tinkered with the window and I'll be damned if I can find a way to free it from the frame.

Anyone know if this is possible? Here's a couple of closeups of the slider that needs replacing, just to give you an idea of the style.
