Megajolt Tune won't save files

[4600cc]

I'm running windows XP Pro, latest megatune (but previous versions have this fault too), java VM from Sun. The problem:

I can not save map. Megatune won't save the map. When I load map from controller, I can save it into a file. When I load map from a file, I can save it as into another file. But when I load map from a file and modify it, I can not save map into the same file, it won't do anything, no errors, modifications are not saved that's all.

I had this problem on other windows XP and 2k machines, so this has to be problem with megatune, java, or something else. I am willing to do anything to help resolve this problem. Please help.
