The operator is probably worn out. I had those type windows when I lived in fla and HD sold the operators ...... but that was 20+ yrs ago.
I never use any kind of grease on the side tracks as I feel it only attracts even MORE dirt. Silicone spray is usually my choice, but on aluminum windows, I douse them with Alum-a-lub. Taking the sash out and really cleaning the track well is probably the answer. If you can disconnect the crank arm from the sash and manually raise and lower the sash, that will tell the tale of where it's binding and why. Generally I've found that most aluminum windows are just a giant pain in the neck and that they practically need to be wet with lubricant in order to slide smoothly, otherwise they will often shudder as they operate. Then when the lubricant dries its back to the binding and rubbing again. I'd really recommend you pick up some alum-a-lub.
