Outlook Express hangup

I have 2 computers networked together. Both are running Windows 98SE, Internet Explorer and Outlook Express 6, updated to the max.
On OE 6, on some e-mail messages, trying to print the message results in a “Not responding” condition on the task. The printer dialog window does not even appear.
Internet connection is through a Cable modem.
I am not yet certain that the problem relates to messages sent from corporate mail servers, but I strongly suspect that most of the problem ones are such.

Any suggestion?

thanks
