Hi, firstly, hope this is the right section to post this in! I've had a search on here and google and haven't been able to find the problem I'm trying to fix. The last few days i've found that the menu bar (at the top of the screen) doesn't always change to show the application I'm currently using. So say i've got itunes and firefox open, i go to firefox from itunes and it will still show itunes in the menu bar and i normally have to hide and then show firefox for the menu to update.. I use this mac for design so use photoshop, illustrator, indesign, flash basically everyday and so far haven't had any problems. And this seems to happen when im using safari and firefox mainly, switching between everything else seems to be fine. I haven't updated these and it's getting to be a pain having to hide/show everytime I switch windows.. Basically i'm running Leopard 10.5.8 on a 24 iMac 2.4ghz 4gb ram, has the mac since Jan 09, bought the SL upgrade back in October but still haven't used it (as I've been worried about the problems with cs3 and cant afford to lose the programs I use everyday..), maybe its worth upgrading? Only other thing I can think of is I setup time machine on an external drive and i plug in about once a day for a backup, but don't think this would effect browsers? Sorry for the long post, any help would be great!
