for a long time i used version 6.2.7-3 q16 dll on my xp sp2 with no trouble

recently i disinstalled that version and substituted with 6.3.6-7 q16 dll

unfortunately on this version the simple command

convert -size 100x100 xc:none test.png (but the same with .gif and .miff)

create only a black square with no transparency.
I tried also with 6.3.7-3, deinstalling the other version, cleaning manually the register and made sure no environment variables are there, but the result is the same.

The same procedure on another machine with xp sp2 work painless...

Could be some system library that can i check for difference between the two machines?

Thank you.

I tested this on my Mac version IM 6.3.6.4 and it works fine for me. I get a 24-bit black image with an 8-bit overlay channel that is fully transparent. The resulting image is RGBA 32-bits.
