I have yet to get over 48 hours of uptime with win2k/xp. The programs might stay running, but my mouse goes wonky, or I can't right click open a drop-down menu, or explorer crashes and doesn't reload (i.e. no taskbar). Ecc on or off, 48 hours is the absolute limit.
Now, Mandrake 8.1 on my laptop is one stable mother. I had it running a puny ftp server for an entire week straight. Granted, I don't know how to burn disks, or play Icewind Dale/Jagged Alliance 2, but having that computer on for one week straight gave me the willies. I had 'impending doom' syndrome every time I pulled it out of screen saver.
And here's my new WTF?! rant: What's up with the 'this program has encountered an error and will now close' box? I got tired of seeing it, and just left it there. The program didn't stop, didn't crash, and I just kept using it by moving that 'crash' box out of the way. Is it a 'proactive-chuck-it-before-it-bsod's-the-os' kinda' msft thing? What good does it do if you kill the serial killer when he's 2 years old (i.e. before he starts whacking people)?
