CRITICAL BUG:
Though the new versions of Bartender4 let you dismount (much better!) the latest release (1/6/09) **prevents you from using any of your mount's abilities**.

(Symptoms: all bars except bar #1 are hidden. Bar #1 however, retains all your normal spells.)

Please be so kind as to fix. What may help is if you test in The Oculus on the drakes (or maybe the daily up in the sky in Coldarra? not sure), but I definitely tried this in The Oculus and unfortunately had to logout, download latest, log in (party waited 5min), realize abilities could not be used, logout, disable BT4, log in, fetch all spells from spellbook, reenable normal bars, and relearn how to play my char on-the-fly with a completely new hotkey setup. It unfortunately took 15min total and resulted in a wipe when I could not heal correctly.

This is not to say BT4 is bad. On the contrary, it's a wonderful addon, but with all the new raid content involving mounts and taking control of things, one needs to rest assured that in the middle of a bossfight one won't be locked out of the GUI and unable to do anything, or at the very least not have to make one's group wait or possibly cause them to wipe.

note: no red error text
note: mount bar had only one thing: the "exit" button

reproducing tips: drakes in Oculus, maybe even other mounts with abilities

suggestion: would be nice if one could temporarily disable BT4 as a workaround during mounts, as the default UI is rather nice (though bulky)

note:
of interest might be the following post on the forums of Dominos, indicating that THAT addon has the SAME problem.

Mounting any vehicle only gives me the exit option in the vehicle bar. Do I have something misconfigured or is there some sort of conflict causing this?
