I do not understand your question, but one problem you may be seeing is that Screen4 does not get the path correct, so it does not display the bitmaps that are in your bitmap folder.
The only way around this is to move the .set file and all its bitmaps to the Mach3 folder and to Mach3\bitmaps
I have asked Brian about this and he has tried to fix it but for some reason it is to deep into the Screen4 code to fix
