Re: [Lynx-dev] Strange behavior

[Travis Siegel]

I've never used brltty, so can't speak to it directly, but I have used 
ubuntu (and still do), as well as screen and another one I can't remember 
at the moment, and neither one of those caused lynx to abort when 
switching sessions.  It might be worth asking on the blind linux list, or 
on the brltty list (I don't have the info for joining those lists, as I'm 
not a member of either one, I tend to use linux without braille, only 
speech).
It's possible it's something in brltty (which would make sense), though 
why it would do this, I have no idea.  However, I understand the brltty 
developer is quite responsive, and may even log directly into your machine 
(if possible and given permission) to fix issues, I know he's done this 
before for others.
It's likely asking him would do more good than posting here.
I do use lynx periodically, but most of my linux/BSD machines are having 
trouble, so I don't use them as often as I'd like, other than my softcon 
site, which is actually using a virtual host from linode).
