Hello mastercam users, I have 2 issues plaguing me. but otherwise like X2mr2

1- I can not figure out how to change default file locations, for example, on one of our seats, when I go to save a posted NC file, it opens up a location that never gets used for that purpose, this also happens when I go to save a STL file. I would like to assign a location for any similar action and not have to re-path, so many mouse clicks wasted. Is this a solvable problem? I have found the area in config. to change where mastercam looks when getting a .MCX drawing file just in case I seem really lost ha

2- I have a favorite toolbar config. I like but no matter what I do, it sometimes reverts to a old toolbar. I also have found where .MTB files are set as a default but I must be doing something wrong. any hints on these issues would be greatly appreciated.
