Eveytime im in a instance i get this error when ever a boss is engaged.

15x [ADDON_ACTION_BLOCKED] AddOn 'BasicUI' tried to call the protected function 'Boss2TargetFrame:Hide()'.
[string "@!BugGrabber\BugGrabber.lua"]:519: in function <!BugGrabber\BugGrabber.lua:519>
[string "=[C]"]: in function `Hide'
[string "@FrameXML\TargetFrame.lua"]:112: in function `TargetFrame_Update'
[string "@FrameXML\TargetFrame.lua"]:178: in function `OnEvent'
[string "@FrameXML\UnitFrame.lua"]:917: in function <FrameXML\UnitFrame.lua:915>

I have done a ccouple of things to the frame but its just apperance changes here is the code.

I am not showing nor am i hiding the frame why do i keep getting this error?
Could it be do to the MAX_BOSS_FRAMES?
If so what would be a better call?

Thanks in advance for any help.
