Not sure if I have a problem or not so would appreciate some advice. I've a new 12" iBook and I'm delighted with it. However, it appears to have one quirk which I'm not sure is something that I can fix or not. I only tend to use the laptop for web browsing but have noticed that after a little while of use, when using the "back" function (for example when browing a forum thread and then returning to the main list) I get the beach ball and the page takes a while to load. I'm only using the one program, I wondered why I was getting those pauses. I was wondering if it meant that the program was using virtual memory instead of RAM and this was slowing it down. I'm happy to add more RAM if it will fix the problem. I don't think that it's a problem with my internet connection as my daughter's laptop doesn't seem to have the issue. I know other threads have indicated that the beach ball can appear when the computer is dealing with a number of progs open at the same time and runs out of memory. As I'm only using the one prog I just assumed that the only delays would be caused by the internet connection. I'd be grateful for any thoughts.
