Roland,

This is great, thanks! It sounds like you corrected some annoyances I 
have been having with gschem and I am anxious to try it out. Any idea 
when the 1.9.3 version will be released?

I just checked the

http://wiki.geda-project.org/geda:download

website and it is still showing 1.8.2 as "stable" and 1.9.2 as "unstable".

Thanks again for your hard work.

Girvin
