[Pan-users] article title search bar timeout

[Will]

I have several large binary groups on my machine that I often access from 32 
bit linux.  
I try to type a term in the header search bar, but if i mess up and hit a wrong 
key or pause
for a second or 2 by accident, then pan will run out of memory and crash, 
trying to 
display my uncompleted attempt at typing what I wished.  I have searched 
through the
pan code, and have been unable to find where the input is taken and the timeout 
is 
set.  Can someone give me a pointer to the file and or variable name of this 
timeout value, so that I can raise it or rid myself of it? Thanks.
