i agree with the other posters. While gaining muscle mass (in the sense of the red fibery stuff) is a very slow process, it is a common response for your muscles to retain water. This increase in your lean mass can lead to little change in the scale even as you are burning fat.
Strength training IS a very effective fat burner, but it means you are going to be burning fat, but adding some lean mass.
Getting your body fat percentage tested is probably the ideal way to track your progress, but this isn't always simple and easy. Tracking inches lost is simple, and is a much better way of tracking your overall progress than using the scale.
It sounds like you are doing great - the only problem is the measurement system.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
