Jean-Claude,

I have not encountered the above problem.

I did find this, and it was because you named the ECW file
with the same base name as the .HDR file.  Because of the order
the format drivers were being tried, the file got opened as a
raw BIL file using the .HDR instead of as an ECW file and the
result was garbage.  In "trunk" the EHdr driver has been
demoted to help avoid this sort of problem.  But I would discourage
you from using the same basename as all the support files or you
may encounter surprising interactions.

Best regards,
