[Inkscape-user] Missing fonts in Inkscape

Hi all, My problem is that although I have several (10) members of Neo Tech font family, and most of the applications can use them, Inkscape sees only two of them. Actually, these two were modified. Do anyone know about a possible reason? I have Windows XP SP3, I have just installed Inkscape 0.48 (I had 0.44 previously with the same failure). Background: Although Inkscape has been on my computer for years, I didn't use it, because I have Corel too and it seemed more convenient. I work for a producing company (Semilab), and we used to give the labeling of our equipments to screen-printing companies. The designs that are screen-printed are given to these companies in .cdr files. We are thinking about changing from Corel to Inkscape for this purpose, as the number of copies of Corel we have is limited, there are incompatibility problems between versions, and Corel is expensive. But we can do this only if Inkscape is equal to Corel in performance in the limited way we use it. This doesn't seem to me a very strict criterion, as we do very basic things (typing, drawing basic shapes, our logo), but includes using all Neo Tech fonts we have. Thank you Abel
