Hi Nicolas, I finally managed to download V.0.2.1 on a PC with win 2000 operating system and have had one system freeze, and a number of system hang ups (go-slows) Operating System: Windows 2000 with all the latest updates, processor P4, 3.0 Ghz, hyperthreading. Open Tasks: MS Outlook, MS internet Explorer, Explorer and Chaoscope Choasscope work: Searching and rendering (plasma) Unravel Attractors Symptoms: (i) Change Task to Outlook, no response in MS Outlook change to IE very slow response change to Chaoscope, close attractor window, system restores. (ii) change task to Outlook, complete task freeze, no windows would update, managed to shut down normally (Ctrl Alt Del, Taskmanager, Shut down) after numerous error windows "TASK XXX not responding" and clicking the close option. These symptons I have not had with Version 0.2.0 but then I did not use Unravel that much before. I will reload the old version and do some more tests. best regards Anton ___________________________________________________________ALL-NEW Yahoo!
