Full-Screen Application Issues

There is a problem when fast-switching (Cmd-Tab shortcut) between full-screen applications.

In the demonstration video below, you can see that I enter full-screen in iTunes. Then I fast-switch to Safari. Then I fast-switch back to iTunes. What we get is iTunes with whatever other window happens to be open. (In the video the Equalizer window is open). If the Equalizer window was not open, then we would see NO windows at all for iTunes, which shows how ridiculous this bug is.) In order to see the window that was full-screened, that window needs to be manually selected in the Window menu item/the application icon in the Dock must be clicked.

In the video, here are the steps:

  1. Make the application full-screen (iTunes).
  2. Fast-switch (cmd-tab shortcut) to another application (Safari).
  3. Fast-switch back to iTunes.
  4. The window that was full-screen now doesn’t show, only another non-full-screen window (in this case the Equalizer).
  5. In order to get to the full-screen window, the menu item Window > (window name) must be selected, or the application Dock icon must be clicked.

How Much Free Space?

I sync my iPhone with iTunes. I like to have a local backup. Occasionally I get a message like this:

iTunes. Updating phone OS 01

Yay! An update. Let’s click Download and Update.

iTunes. Updating phone OS 02

Oh. Let me have a closer look…

iTunes. Updating phone OS 03

I’ve 1.36 GB of free space. That’s greater than the 770 MB that’s required. Let me sync the phone and see how much free space there is afterwards.

iTunes. Updating phone OS 04

Wow. 3.30 GB. That should be enough for the sync.

iTunes. Updating phone OS 02

Hmm. Let’s check the iPhone itself.

iTunes. Updating phone OS 05

Well, I guess this figure of 411 MB is the number that the update process is seeing, and no wonder it’s complaining. But, why is iTunes giving me such a large figure for free space? Shouldn’t it be querying the iPhone itself and getting the phone’s free space number?

It may be that my iPhone needs to be restored. But even so, iTunes calculation of free space is not the same as how the iPhone itself calculates it. Which one is right?
