IT might have happened because....
Someone else might have added or deleted something from the menu before you resaved it on the Network.
Say
Guy "A" (you)
Guy "X" (other worker)
If "X" is in CAD while "A" is changinging the MNS file "X"'s CAD station won't look at it untill he closed the program an reopens it.
After "A" saves the the MNS file, it needs to recompile on each station, do to the networking of it. IF "X" changes his menu's around, adds, delete's or anything it will save to the MNS file after accepting the change.
THis would screw everything up beacause now "A"'s Changes were just saved over by "X"'s change.
Hope that made some sense
I had this problem also. I use to use one Menu File, thinking
"Ok, cool if I change or add stuff for the company (cause I am CAD Manager) it will update on all machines."
Well, I had big problems. Every User likes to move toolbars, add to them. close them or some will even just delete them if they dont use them.
Once I lost an entire set of toolbars and buttons and there were abunch of new ones that some guy added. I freaked out on him and then went to making a master MNS file and loading it on each machine this way if they change it or screw it up I know It wasnt my fault. IT can still be easy this way since it is a main file you just change the master and then replace they once you previously loaded on the machines, more time consuming then networking but gets around the problem.
Be warned though you will get the guys that say I want my old setup back. Tell them too bad. Either that or create a profile before replacing that MNS file and then reload the Profile after you replace the MNS file.
That's my Advice...hope it helps.
