Help please...Covert dungeon..

I have been hopelessly stuck in the covert dungeon for ages. I cannot find the hidden buttons to open the gates and I have clicked on absolutely EVERYTHING many times over I have tripped 3 in the room with the tables,but apparently there is another one there. I have found none in the throne room. Can anyone see what I can't?

I'm really pulling my hair out over this one! I've completed 6 other dungeons, and, while I had to hunt, didn't have nearly as much trouble with the hidden buttons. Any help would be greatly appreciated.

The rooms are always opened successively: in the first room that is open at the beginning there are triggers for the next room, in that one there are triggers for the next, and so on. So you don't have to look in all rooms, just the last one. There's a trigger in the throne room, so that would be the last one for you - you already found all triggers in the bench room. In the throne room look between the arms on the wall, above the chairs - there is a trigger above the second chair from the left. There might be others of course, but they would certainly be in that one room.

Thank y thank you!ou so much! I was driving myself crazy! Once I saw it, it was impossible to unsee. I must have clicked around that area hundreds of times but missed it.... and it was so obvious once seen!Again..... thank you!
