Firefox freezes on print -- anyone else?

I've been having a problem with Firefox 1.5 running under SuSE 10.0. When I print a web page, I get the correct printout and the printing window shows 100% completion. But the printing window won't close no matter what I do, and in fact the entire machine seems to be freezing up. Has anyone else encountered this problem? Googling for it has produced nothing. Paul
