Awp doesn't shoot in Counterstrike 1.6

I am having a problem shooting the awp in CS 1.6. When I shoot my awp after quickswitching from a deagle or knife, I hear the sound and the awp seems to shoot, but the bullet count is still the same and the shot does not register at all. here is a demo of what's happening click dfd.dem to download

Is there a way to fix this registration problem? Thanks!

they removed the ability to shoot immediately after switching from your pistol a while back - there is now a slight delay.

jsut get used to playing defensive with it and cursing furiosly when u get caught in the open and jump around like a sitting duck when u've emptied ur pistol clip and try to get another shot off
