frame devidor

[Ben Frantzdale <frantzdb admin arhs net>]

On all of the GTK themes I've seen, the "frame devidor" (ex: the seperator
between the tree and file windows in gmc) can only be "grabed" on a small 
square near the bottom. This appears to be consistant with Motif,
but I see no reason why it should not be able to be grabed from any point
on the devidor as in windows and (I think) MacOS.
Is there any reason for this?
Is it just a theme thing?


Thanks,
