1. Dropbox. Even though I found a walk around to get it work, but I didn't bother. I'm using iDisk for the time being. 2. Screen saver. This is strange, because I notice nobody else but me faced this problem. What happened was I chose my screen saver as "iTunes artwork" (because in Lion, that screensaver also works as a mini iTunes player -- you can try it, pretty cool) and set it at 10 minutes to be active if I'm afk. But sometimes even while I'm typing essay or coding, the screen saver just got in the way. I tried to cope with it for a few days, but today I decided to turn it off by setting the time to "Never" (there's no option to deactivate screensaver, as far as I know). Does anybody else also get this problem but get a solution? Please let me know. 3. Audio jack making weird sound. I found a solution to this: simply go to Audi MIDI Setup, then change the format to "2-ch 32-bit". 4. Font! This is really really annoying. I notice that whenever I go to any website that has *code* or *link url*, all of the texts will rendered like this. I need help with this asap because it's super annoying. Note: it only happens on Safari. Apparently, it works fine on Chrome. 5. 1Password extension and Click to Flash for Safari don't work. 6. iOS-like reverse scrolling is apparently unable to be turned off on a 2008 MacBook. I can turn it off on my MBP 15" 2010 though. I'll update if I come across any other problems.
