Need to refresh a dozen times for php pages to load

hello people, i have apache2, php 4.3.2, win XP, mysql4, fairly fast comp. i'm hosting phpBB 2.0.6(latest) forums on my comp for the college LAN the speeds r very good so that's not a problem problem is that people have to refresh their pages somehitng like a dozen times before the page shows up...other times, just a blank page shows up. php is properly installed coz the forums work perfectly when they finaly load. barely 5-6 ppl post on it right now so flooding cant be a problem... i've tried asking this in the phpBB and apache forums but they can't think of a fix. all that's left is PHP,. i hope u guys can help i've spent 4 consecutive nights reading manuals and mining the net for a solution but all i found was 1 other person wiht a similar problem on google's usenet thingie...who also got no answer im not sure when this started coz no one told me about it before... HELP! my exams start in 4 days and i can't get any sleep coz of this ... did i miss out any info? thnx Karan Rawat __________________________________ Do you Yahoo!? Yahoo!
