Frequently getting stuck while crafting

Steps:
1. Sometimes when initiating synthesis, I will get stuck and cannot move.
2. The synthesis animation does not occur, but I do still gain skill points.
3. I am unable to begin a new synth, interact with NPCs, or open my equipment menu. Doing so gives me the line "You cannot use that command during synthesis."
4. The only fix I have is to force quit the game and log back in, after which I will continue to craft, only to run into the same problem after a short time has passed.

Might be that you have your FPS set to uncapped thru other means, you don't have to confirm that here but try to change it to 60 FPS and see if the problem persists.

Are you using third party programs?
