Well i am just a member like you. I am not a Mod or Admin. I know you stated this is an old machine so my only advice is to upgrade to a new machine and get XP. I have used 95, 98 (1st and SE), 2000 (Pro, Server, Advanced Server), XP (Home and Pro), Server 2003 and Vista (Next OS from M$). Since Vista is only a Beta and not complete i would suggest that you get to XP ASAP since it is the most stable (cant believe i said that about a M$ product) OS out there. Aside from Linux or Mac OS X. I use it for graphics and much, much more with few to no errors.
I do not accept support questions via EMail, PM, IM or my G+ page!
