Body Text doesn't display when viewing messages

[Paul Fielding]

In IMP 2.2.6 on linux, connecting to a Lotus Notes R5 server, I find that 
roughly 95% of the messages I receive, when I view the message, the body of the 
text is empty in the message viewing window.  If I click on the 'message 
source' link, I can read the entire message, but that's not very pretty.  The 
interesting bit is that a few messages do actually display.

Anyone else seen this or have any ideas on how to fix?

regards,

Paul
