@Jeremy: Both ideas sound nice. The first one seem to require lot of work, but I think it can be done with som effort and time. The second one...I just can say "Wow, how the hell do I do that?" I'm just a beginner programmer, so I want to start making usefull-silly-small apps and with time, plunge me into larger projects. Anyway, for now I will stick with Reg File Merger and its main use: merging reg files. Offtopic: I love to hear again and again that "MMM-M-M-MONSTERKILL-KiLL-kiLL-kill..." too.
