I hope this works for pictures. This is my hanging window.
This window should have FUZZY FELT window seals (you should see a fuzzy material in the side tracks).
Candle wax should do the trick on this type of seal but it may take some work getting the wax on the track and window frame.
You should also have on one or both sides a spring loaded counter balance (it typically is hidden under a metal cover in the non moveable top pane track). There should be a string from the spring to the bottom pane. This spring is there to hold the window open but it may also "assist" in the opening of the window.
Some sliding windows are simply a pain, I have one that gets stuck easily after sitting for the winter. Takes a few good hard pulls in the spring and then it is good for the summer..
