This is the seventh time that it hangs on me and I need to retype evrything again to post my topic in mylot. This time this is not about the internet or wifi access, this is about my netbook that keeps on hanging on me even that this is brand new. I purchased a new netbook to replace my old not-so-working fast Samsung Sens Tell me if it is because of the memory, specs and programs that I have installed in. Let me know how to improve my netbook's working performance (Kinda hate typing now since I have been doing it for the past 45 minutes of reposting again and again as I shut it off and turning it back on; keeps on hanging and there goes th cycle!) Thanks and happy mylotting about your gadget tips. ^_^-)
