I have been 'snowed under' - I do care and thanks for your reply.
Error logs - didn't show up anything untoward. (System and Apache)
Could it be something to do with the proxy server built in to apache 2?
Strangely enough, when I access the site over a fast WAN connection (the box is on an intranet) the problems seem less noticable.
Other than apache / php / mysql I have samba and webmin running - so although the server is only a p2 350 with 128 Mb of Ram i THINK that is a high enough spec. The smb shares that I have created work v. fast.
I hope this goes some way to reaffirming your faith in humanity.
Cheers
Neil
