It really breaks my heart to see Apple getting lax on their own UI guidelines.



Yes/No buttons are so Windows. Yuck!

And in which way exactly should they have put it?



According to Apple's own User Interface Guidelines, buttons should have verb names, action-oriented names. They buttons themselves should be enough to decide what to do. Instead, when using Yes/No buttons, the user is forced to read the entire dialog text and then make a decision about whether they need to click Yes or No.

From their guidelines:

Using a more focused button name, such as Erase, Convert, Clear, or Delete, helps make sure that users understand the action they’re taking.


In the example dialog that I provided in my original post, the buttons could've been named "Keep Episodes" and "Delete After Played".

hey bud :cool: your wifi problem worries me.. wifi implants have yet to pass FCC approval and may not be suitable for all, This is most likely the cause of your problem and I doubt that this software update will help you out. You should probably have this surgically removed before you keep hurting yourself.

Speaking Safari, it very frustrating to watch Safari start to load a url and then stop. Happens a lot. Have to hit the stop button and then the refresh button again, to get it to completely load.
