MSIE & GZIP problem?

I have several browsers installed; NS4.x, NS6.02, Opera 6.x, and MSIE 6.0 -- I'm using gzip compression on my site through the ob_gzhandler. My pages seem to load fine, however, ONLY in MSIE when I REFRESH (i.e.. with the Refresh Button) the page seems to lose it's table or table format, and everything looks all jacked up. This ONLY happens on a page reload. The other browsers don't seem to have this problem -- I went to MS's Windows Update, and installed several updates, mostly Security updates -- there were no updates that spoke of a gzip / reload problem -- nonetheless, I applied all I could. After rebooting (again) -- I went back to my site with MSIE 6 -- hit reload and now the problem has gone away. Has anyone heard of the problem with MSIE 6? If this is a known problem; I'll have to perform some browser check to make sure I can gzip to that MSIE version 6 build (whatever) -- kind of a hassle. I just did a search on Technet, and could find no mention of it. Thanks. Jason
