Strange hotbar error
 

This has only been happening since the last few patches.

I have 6 hotbars on top of each other in the bottom center of my screen. The top bar is the only one exibiting this problem.

During any fight in a Raid, the 1st 9 buttons of my top toolbar (bar 6) become unclickable!! i can release them by clicking button 10 and cancelling the spell, buttone 1-9 can then be clicked.

When this happens, there is no mouseover effect on the buttons and they do not move when clicked.

Told you this was strange!

What will i need to do to gather information for you to diagnose this apparent issue? Screenshots sown nothing but the position of my bars.

Move your raid window away from your hotbars (press F10 to see the transparent part of it)

Ah, maybe i need to post a screenshot - raid windows are on the right of my screen nowhere near the hotbars, but checking the window placement of everything else is a good idea.

I'll report back when i've checked everything.
