Well that rules the cache out as being my problem then :-(

Yes, but only in my plugin and only on a certain page of my plugin.  
I've reproduced similar code in a dramatically cut down set of code  
ad it works as expected! So, there must be something somewhere in my  
code but I'm damned if I can see it!

The really weird thing is that this works on my localhost sandbox  
setup (Mac OSX, PHP4 and SQL5.0.27) but not on a server (Linux, PHP4  
and SQL5.0.27).

My other issue is some pages don't load on the server as they should  
and since my host is currently upgrading their webhosting servers I'm  
beginning to think that may be the cause of my problems.

I'll keep looking :-(
