Stucco or EIFS? It sounds like a classic EIFS problem with moisture generated in the home unable to dry to the exterior by diffusing through the exterior walls because a waterproof membrane (EIFS) has been installed instead of a moisture permeable membrane.

The walls are solid concrete, the windows are double pained aluminum with aluminum tracks. The windows are covered by a 10' covered patio. They are the only ones doing this. I have the same window installed in my bedroom to match the new addition on the front of the house and they are not having the same moisture issue. The windows are mounted on PT bucks and then sealed with caulking. All the other windows in my house are single pane awning windows and none of them are doing this. Thanks everyone for your help.
