Client Alt+Tab Issue

PC Windows 7
CPU Core i7 3930k
GPU ASUS HD 7970 DCU2T
RAM 64 GB
PSU 1200W
MOBO ASUS RAMPAGE IV EXTREME
Game installed on SSD Corsair ForceGt3 nothing else but OS is installed on this.

Alt tab + alt tab = proper resume
Alt tab + clicking on icon on taskbar = FFXIV has stopped working
Windows key + tab key = proper resume

FFXIV crashes on returning to the client after having alt-tabbed away from it.

Time: various 24/8 GMT
Frequency: about 3 or 4 times now
World name: Ramuh
Character name: Lotsutsu Lotsu
NPC name: n/a
Monster name: n/a
Class/Level: various
Party or solo: solo
In-game time: unknown & various
Area and coordinates: various
Steps:
1. Alt+tab away from client to browse web
2. Return to client - I normally do so by clicking on the taskbar.
3. Get message "ffxiv has stopped working" and the client closes down.

NB - it doesn't always happen. It's happened about 3 or 4 times now since Early Access commenced.
I don't know if it helps or not, but below are the messages recorded in System Information/Software Environment/Windows Error Reporting. The same two messages are repeated on 3 occasions - 10:59 24/8/2013; 17:57 24/8/2013; and 18:58 24/8/2013. These times must be GMT as they don't match my local time. The two repeated messages are:

(1) Windows Error Reporting
