I found 3 other threads on Alt-Tab Crashing, but *none* of them were using Square-Enix's Official Bug Submission format. (FYI: If you don't, SE will ignore and move the bug to Insufficient Info - This is what they've done since Alpha.) So here's a Full Submission of the Alt+Tab Crash Bug...

To: FF XIV Dev Team,

For 2.0, since Beta Phase 1, I've been able to successfully ALT+TAB key to switch between Full Screen Mode in Final Fantasy XIV, and going to other applications (great!).

However, with the official launch of Final Fantasy XIV: A Realm Reborn, using ALT+TAB to switch out of the game and, say, check on info in your Web Browser and switching back to FF14 after, will CRASH the game, almost 100% (sometimes I get lucky and it doesn't crash). But it happens a LOT now.

Please fix this! (Using latest Nvidia Graphics Drivers as well.)

Time: 4:24 p.m. Pacific
Frequency: 90% (some people 100%)
World name: Masamune
Character name: Kiara Silvermoon
NPC name: n/a
Monster name: n/a
Class/Level: Arcanist / 50
Party or solo: Both situations
In-game time: 8:30 a.m. Eorzea
Area and coordinates: Anywhere in the game.

Steps:
1. Load up Final Fantasy XIV in Full Screen Mode. (FYI: I run an Nvidia GeForce Graphics Card (660 Ti) with latest Nvidia Drivers.)

2. Once in the game (anywhere), proceed to use ALT + TAB keys to switch out of the game to your desktop. Proceed to use Firefox web browser to search some information (or any other application).

3. ALT + TAB key back to Final Fantasy XIV.

Result: Game Crashes.
