On the note: WinME itself has a memory leak issue. Not giving back memory after a program closes.
I'm running Win98 myself on a Athlon 500Mhz with 128Mb and can run XoloX for days without crashing. Only when closing XoloX it may occasionaly crash. On the system resources:
While downloading multiple divx files I'm able to watch a Divx fullscreen without problems.
So I'm wondering what specific environments (eq. other programs running, amount of downloads, memory, OS, number of shared files etc..) people are running that are experiencing the crashes. Maybe the XoloX team can determine that way what is the dominant factor here and eliminate it.
