Thanks CJ
I found some advice on a Windows 98 site last night and did what you have just suggested.
Memory figures have zoomed up with USER free at 54% and GDI free at 78%
However I still have the following on the Start Up list.
Logitech Desktop Messenger agent (something to do with keyboard or mouse?)
Navapw32 (not a clue) CConnect (broadband link?) Rnathchk (no idea) Gmt (not a clue) Ptsnoop, Rundll32, CMesys, EM_exec, CSinject (all no idea, junk put on by my son, I suspect) Nprotect (Norton virus check?)
Can I safely dispose of the mystery files?
