cures and abilities droping from group/raid window after an LD

[tntent]

Whenever i get an LD and upon my relog of the character i find that my click to cures and my quick buttons do not work either i get an error message saying ability is no longer available like it isnt in my knowledge book. The fix that i have found is i completely restart my client. This has only been a problem since the recent LU. I have made sure my profit is up to date as well as those two files taken off my ignore. Any suggestions as to how i fix this would be greatly appreciated. Thank you.
