Whenever I press P in the Rage console it opens the pause menu. If I exit the pause menu and console, the game is frozen, and I have to go into the console once again to unfreeze the game. While it does not take away from overall gameplay, this is simply annoying to deal with. Help?!

Rebind your pause button and you should be alright. Not sure if you use ELS or not, but I would've rebound the pause button otherwise every time you open up the ELS ctrl panel your game would pause. 

change the keybinding of your gta v pause menu there is a primary and secondary key. change the secondary key to the menu key which locate next to the right alt key or change it to something else that doesn't conflict with something. that should solve the problem 

I had this issue once before and reinstalling the game appeared to fix it, but I don't feel like doing that so I'll just change the keybind. Thanks.
