Problems with individual toons keymapping

[Qyre]

When I run one toon, everything's fine. Jump to another, and the 'e' doesn't function (eg: to pickup items/interact/etc).

SO, I can go in and clear the binds, rebind, then it works for a moment.
Hop to another toon and it may or may not work as was previously set.
Then hop to another toon and that one doesn't work. Hop to another and it works fine.

Even after I've gone through and cleared, then reassigned each toon (that didn't work as expected) to using 'e' for interact, once I log, the next time I come back, it's hosed again.
Out of 15+ toons, I've got at least 4 that consistently have this issue. And several that consistently function properly.

Any clues or suggestions? Not really sure if it's due to the soft-targetting issue as of late, or if it's something else. But I'm about fed up with it.

----------------------------- THE FIX!! ---------------------------------

Finally after going through all manner of insanity...logging in/out of 13 toons to verify settings/etc...

Even though all 13 toons had the "Toggle Auto-Targeting" cleared (no key bound), and were not in use, resetting the "Toggle Auto-Targeting" and then cycling through enabled/disabled a few times, and then clearing the "Toggle Auto-Targeting" (while enabled of course) again seems to have fixed it.

Not sure if it was a crash while on these toons at some point that jacked things up, or what... but re-assigning a hot key to the toggle, and cycling through it a few times, cleared it up! *whew*

Hope this helps prevent someone else's frustrations.
