I just now have dual core... :) I am hopeing for a huge increase in speed mostly because of the amount of memory involved and ya I can use sdl.. ... The installer doesn't like it :( that is probily not my biggest problem but it is worth noting.. I haven't checked to see if just copying the files over from my old computer will do the trick or not.. I seem to be missing the drivers that are used for dex tracker when I moved it to vista, seems that alot of the python installers are useless but most everything can be built from the code... I would be more than willing to test and fix for linux, mac, iphone, kids laptops exc if they give me a chunk of shares of the battery company (the one berkshire bought) that makes them until then I just get to test and get disgusted with windows.
