This is a little off-topic, sorry.My old gaming computer that I've now re-formatted and loaded Win98SE onto for other uses: After loading Norton Internet Security 2002, now I get a Windows pop-up "Your system is low on memory, please quit another application..." when attempting to load other software, or even attempting to to install NAV Live Update files. This always appears to be at the point in an install where the progress bar indicates the actual install taking place. I've never seen it before I installed NAV today- I've currently got that disabled but it still occurs. I'm reluctant to un-install NAV, as I've heard that residual registry entries can prevent a re-install (??). I have 738M of PC-100 RAM, a PIII-700, ABit BE-6 mainboard, SB Live 5.1 sound, GeForce 2 Ultra video card. I'm running DirectX 8.1b (latest).Any ideas on what could be causing this apparently incorrect message? (I have my swap-file set to auto (default) with about 1.3G on C: free.Thanks for any ideas.Bruce.

Bruce, Bruce, Bruce, Bruce, Bruce!!!:-lol See the following about Win98:http://support.microsoft.com/default.aspx?scid=kb;[LN];Q181862http://support.microsoft.com/default.aspx?...b;en-us;q253912http://support.microsoft.com/default.aspx?scid=kb;[LN];Q108079One or more of these should help!!

Oh "doh"!!,Thanks very much for the lead on this. As soon as I saw VCACHE in the FAQ items you referenced, I figured it out.This computer (an older one that I built myself some 3 years ago) originally had Win98SE on it (with a max of 512M), then I installed XP, and upgraded memory to 768M. So, I'm here scratching my head "it used to work OK"- not realizing the 512M limit of Win 9x. Thanks for the articles. Maybe some more coffee might get me thinking better!Bruce.
