Unfortunately we can not always choose our customers nor let them buy new
computers ... so we have to get workarounds !
According to my tests, there are "incompatibility problems" between MC, some
video card drivers and some non-really-standard file formats.
- MC display always OK the RVB jpegs, but display sometimes bad the
gray-level jpegs or the "optimized" jpegs.
- MC display always OK the ordinary gifs, but display sometimes bad the
transparent gifs
For jpegs, the workaround is easy : open the files in Photoshop, transform
as rvb images and save as standard jpeg files.
The same for plain gifs.
For animated or transparent gifs, i am still looking for a reliable
solution.

Claude
