Under Win 7 64 bit, I occasionally run into a problem with NX 2.2.4 being unable to save a D3x nef when PM 4.6.3 is open. When I try to save the nef from NX2, I get a "Can not save file" error message. If I close PM (which was used to launch the NX2 and pass off the file to be edited), then I am able to save the nef from NX2.
This doesn't happen every time I try to save a D3x nef, perhaps one out of every five times. Also, it rarely happens with D3 or D300 files.
