Well, I'm having some difficulties converting an SHP into PCX. The problem is that the image output is 2 times larger : the first half is the corresponding image, and the second half is paint in blue... Effectively, a 60x48 becomes a 120x48 !
If you can't see what I mean, I can try to take a screenshot.

The resulting effect, is I can't edit the PCX. The error message is :
"[...] the file-format module cannot parse the file."

BTW, I'm under version 1.35.
