Weird things in FF14

[Lilyarel]

Sometimes when I pull up the menu the curser will appear even thought I'm on the mouse and keyboard set up. I dont even have a controller plugged in so I'm not sure what causes this.

This one is when playing as a BLM and using a 2 handed staff. Sometimes if I get whacked hard enough while casting, my character will go into this weird stand in a weird idle stance where theyre stiff as a board. The stance is holding the staff with 2 hands for the rest of the cast. For a reference look up the THM on the website under the "What is Final Fantasy?" on the Lodestone.
