Compatibility issue in MPD submodel file names between MLCad and Bricksmith

[Philippe Hurbain]

A friend who uses Bricksmith sent me a mpd, that I returned him after some changes using MLCad. After that, Bricksmith complained that "submodels are not available". A check of MPD before and after my changes, showed that there was a capitalization issue.
Here is the header of one submodel:

Code:

0 FILE righttrack.ldr
0 Right track assembly
0 Name: RightTrack.ldr

Bricksmith refers to this submodel as

Code:

1 495 -480 104 59 -1 0 0 0 1 0 0 0 -1 RightTrack.ldr

but it seems that MLCad uses only file field as reference, and silently changes this line to

Code:

1 495 -480 104 59 -1 0 0 0 1 0 0 0 -1 righttrack.ldr

...and now Bricksmith is lost!

Any solution?
