Save as does not save in LDCad 1.5?

[Jaco van der Molen]

Any file. Only first time creation does work, eg. start a new file and save (as).
But saving an existing file under a different name and/or drive and/or folder simply does not create a file.

The only thing I think can confuse is most of the time I simply create a new model by starting a new file and immediately start building like it was a normal LDR file. Then in the progress of building I end up with some submodels and then I save as MPD with extension .mpd.
Perhaps that is the problem.

I tested on two machines (work and home).

I'll take some screenshots or screencapture a movie illustrating the problem tomorrow.
