Quest Picking up the Trail,
when i've came to Citadel and bring "Doc LI" inside, i've got thing like "quest-listen-freez" ... when Quest NPC talk or do somth and i can just watch till they finish.
but i've got perma this mode ... can some1 tell me command to toggle OFF this mode ?

fixed by concole command : enableplayercontrols

Not sure what you mean, but if you mean you can't skip through any conversations then that sounds like a glitch! You can skip through any conversations except for some of the quest ones.

y, its kinde of glitch ...
"Doc LI" already in Citadel Laboratory, but when im going back to main gate , im getting "conversation" : - Doc Li coming again from outside, and again going to laboratory w/o any speach with other NPC ... and i freezed in "conversation mode" ... cant move and cant speak, i can just move camera around.

im sure if some1 post Concole command for turn OFF this mode, i can continue main quest

and y, sorry for my ultra bad english )

Sorry I can't help as I don't play on PC, but there are others here who may be able to help with PC console commands.

I apologize for not thoroughly reading your problem, but here are some useful console commands to help with "freeze" issues:

"cam" - CloseAllMenus, use this command to exit any menu mode you are stuck in, including dialogue.
"enableplayercontrols" - can't move, can't speak, only turn camera? This will enable all functions for you.
"player.removescriptpackage" - can't move, can't speak, can't do anything? This will reset your character's "package", as in disable any forced stances. You might need to use enableplayercontrols after this one.

ooooo yyyeeaaa ... my friend from finland ) enableplayercontrols - thats solve my problem ... tnx ))) thank u ))) idol
