Try spraying Ace brand 100% silicone lubricant on both the top and bottom tracks. It may take some moving of the doors but it will work. I have done this and my Lanai doors open very easily. Avoid lubricants that have hydrocarbon lubricants since that will eventually will become gummy and add to your problems.
BTW, there is an Ace hardware store in Wildwood near the post office. The folks there are very helpful.
