Can't throw a d@*m grenade

[seabass1992]

I have Crysis 1 on steam and I am unable to throw grenades.

I press G and the on screen character pulls a hand back to throw the grenade but nothing happens. I can no longer aim or reload but can shoot sometimes. I have to switch weapons to get out of this situation. I have tried using H to switch grenades, the animation for that plays fine.

Any help would be appreciated.

Not sure if you still need this but I'm gonna post this here in case someone finds this through Google. :)
In your 'Documents\My Games\Crysis\Profiles\default' folder you'll find a actionmaps.xml file.
Open this file with any text editor and search for "grenade". There are multiple instances in the file, you're looking for the following ("g" is the default key):

<action name="grenade" onPress="1">
<key name="g"/>
</action>

Add 'onRelease="1"' in the first line to make it look like this:

<action name="grenade" onPress="1" onRelease="1">
<key name="g"/>
</action>

Done, you can throw grenades again.
