So I didn't see any fix / solution / reply to the issue of WoW crashing to the desktop when one of the toons takes a taxi.

I've had this happen a lot, and I'm terrible at not updating addons, so I'm not sure which version this was. I just updated everyone last night to the newest version, so I'll be able to experiment tonight with this.

But what was hapenning was this:

Group standing at FP. Main has group members enabled. Main takes FP. all 4 slaves crash to the desktop. ( slaves don't have FP window open, or are somewhere else in the world)
Group standing at FP. Main has group members DISabled (/jamba solo). Main takes FP. all 4 slaves stand there (working as intended).

This also happens when any other group member takes a FP, the main will sometimes not crash, but all the other slaves DO crash. As far as I can tell, if the toons don't have the FP window open, and the main (or any other toon) takes a FP, wow will crash. I didn't save any of the reports but it was generic 132 wow crashes. Like I said, I updated to the newest version last night, so I'll make sure I'm still current and test it out tonight to see if it's still there and give you some detailed steps on what I'm doing to cause it.
