Titan Panel & Group Invitation Problem?

[Mairna]

Hi. I have nui Pro installed and everything is working great so far. However, I recently tried to install the latest version of Titan Panel and I believe there is a problem with Titan Panel that interferes with Blizz's default UI. After I installed Titan Panel, i was unable to accept party/raid invites. They kept declining automatically, and I did not have the buttons to Accept/Decline pop up on the screen. I believe I have isolated this to Titan Panel, because I currently do not have Titan Panel installed, and there is no problem with my accepting group invites. Is this a known bug, and is there a workaround for it? I'd really like to be able to use Titan Panel without screwing up the UI. Thanks!
