Alt-tab causes game to crash

[Tsuroku]

So whenever I alt-tab out of the game to check something on my desktop, there's a VERY strong chance when attempt I return to my game, it will crash. It happens about 8 out of every 10 times I alt-tab out. My friend is also having this issue with the game.

I just had it crash yet again about 20 minutes ago when I alt-tabbed, and of course when I try to get back in I'm greeted by error 10102. ._.;

Anyone else having their game crash on them when they alt-tab out?

I had an Alt-Tab issue has well, though the game didn't crash.

What happened was doing an Alt-Tab seemed to open up another FFXIV session. It was really weird and not sure what to make of it.
