Operation Flashpoint DR-Help

[tommybhoy]

Silly question this and I'm probably going to kick myself when I find out how to do this.
For the life of me, when I select a supply crate to resupply my ammo/ change weapons, I cannot leave it when I'm finished, I just get stuck there
Help me please

Tried pressing escape, no joy. Just bought MOH so no arma for me (plus, i thought it was system hog anyway).
