When I try to close a widget on my dashboard or try to add something to a sticky note widget, the adjustment will be fine until I reboot my computer. Then everything goes back to the way it was before I changed it. Essentially any changes I make will not take or save. Any ideas what my problem could be? I am in South Korea and cannot go into a Mac store to talk to 'genius'. I have a macbook that I bought in 2006. I use OS X 10.5.8 (Leopard). Everything else on the computer works normally. Do I have some kind of mac virus? Any advice would be greatly appreciated!
