filter problem in message list

[Jack <ostroffjh sbcglobal net>]

Hello,

I have found an odd behavior in Balsa (2.4.1 under Gentoo Linux, with  
KDE desktop and minimal gnome libs).  If I type something in the filter  
box (defaulting to "Subject or Sender Contains:") it correctly filters  
the list of messages.  However, if I then change what is in the box and  
hit the button, nothing happens.  If I clear the box and hit the  
button, the filter correctly shows all messages, and I can then enter  
something else to apply a new filter.  This happens with any of the  
filters (subject, body, ...)

I've done some searching and have not found any similar problems  
reported.  Any thoughts on what to check - or is this a known issue?

Thanks for any suggestions.

Jack
