Help with Dungeon Doors

[Rongway]

1) Are your Objects nameplates turned on?

/characterconfig
Display Name Settings (red buttons)
NPCs tab
Objects: Display Name Settings: Always


2) Are you able to target the doors with the "Target Nearest NPC or Object" keybind?

/keybind
Targeting
Target Nearest NPC or Object

Set a bind for that and try to acquire a door target with it. Then hit your Confirm key (/keybind, System, Confirm) to interact with it.

Let's see if that works on the door first, and if it does then we can rule out broad problems and look more closely at how the game treats your mouse.
