Counter Strike Switch hand

Cant switch from Left to Rigth hand 

Some times in condition zero or counter strike 1.6 you will notice a strange error, that will not allow you to switch from left to right hand by using the option in the game. when you alt-tabed a lot your gun would switch to left-handed while it still shows right handed in the option menu.
All you have to do is selecting left handed then apply, then select right handed and apply again.

If this doesn’t work, you should be running your game in software mode. Change it to Open GL, or D3D mode. This should fix the problem. If this doesn’t work too, you have no other go than to re-install the game
