It could be any number of things. Like Lumage said, you could have an extra VSYNC somewhere in your own code which is conflicting with the MAP program. I've never used that program though, so I don't really have any good suggestions. Another thing is that the MAP program might be taking up a lot of the processing time, and your program added too much extra processing to be handled in a single frame.
