Mod_gzip problem

I had this problem: IE was laoding BLANK pages. This seemed compeletly random, the pages always loaded OK after hitting the reload buttoon! This was happening on 3 separate win computers in IE, at the same time mozzila, opera, safari = no problem at all. We tried everything, but there was no real pattern to follow, sometimes it happend on one page next time it was fine and happen on a different page. Finally I studied the http headers, that’s when I realised the pages were gziped. I have disabled this in htaccess, and no problem since. Has anyone heard of this before? Search on google on mod_gzip and blank pages returns some results, but nothing concrete. It must be a real problem, we had this on 3 separate machines in separate locations, strangly 4th machine we tested could not reproduce the problem.
Thanks David
