backspace and tab broken?

[Pia Mikeal]

Greetings,

	I am not sure if this is a bug in screen or something else, but 
screen seems to be a package I can take out of the equation and the 
problem goes away.  Here is my issue, at the commandline, my virtual 
terminal prints odd diamond shaped characters to the screen when hitting 
tab or backspace ^? and ^t cause this same odd behavior.  I always run 
screen version 4.00.03 (FAU) and is the default Debian package of screen 
distributed with Kubuntu Hardy Heron 8.04.1 LTS but I had this problem 
after I upgraded to Hardy (via a clean install from CD) even when running 
the latest version of screen I compiled myself.  I am unsure if screen is 
the actual problem or if it is just a clue into the actual problem, since 
this behavior is not exhibited except for when running screen.  This 
problem is also intermittent, but occurs 90% of the time.  I can run a 
session for not long at all before it starts exhibiting this aberrant 
behavior.  Has anyone else run into this or have any ideas about what 
might be going on here?  I have tried to search for this on the web but 
had no luck hunting down other incidents of it on any forums.
	One more odd thing to note, sometimes I use yasr (text to speech 
software) and it has the ability to announce the ASCII value for any 
character, but what displays as an odd diamond shape, just shows up as 
whatever character it should be, eg. tab if it was a tab pressed.

TIA and Regards,
