Crashing while zoning

[tanknspank]

I regularly get zoning crashes. The most reliable way for me to reproduce them is:

- Run under WinEQ2
- Begin zoning process
- Click outside the EQ window (I have 3 tiled screens as my desktop, regular multi-monitor not a 3x spanned one using Eyefinity or the like)
- Click back into the EQ window before zoning has completed, EQ crashes
- If I wait until zoning has completed everything is OK

This is not a "windows thinks EQ has crashed because it doesn't respond as it is busy loading stuff" kind of thing, but rather the process immediately terminating.

This is running on Win 7 Ultimate SP1, 64x on Intel i5 2500K @ 3.60 GHz, 32GB ram, GeForce GTX 780.

Choice of storage for EQ-P1999 doesn't seem to affect it (tried both SSD and classic disks).

Connection-wise I get about 45ms with no packet loss on Teksavvy cable (ON) on Rogers cable infrastructure.
