You, my friend have stumbled across the problem that many people before you have and is the reason using this program is such a pain in the @$$. As the program is set up at the moment, it is impossible to select and pause animations for any of the different models you spawn from the environmental objects bar as you would for the base model. There is a way to work around it but it will cause no end of frustration and crashing, so consider yourself warned. The simplest means of altering an animation is to select the "Edit" button near the model file and from the menu select a new starting animation other than "idle.dat". Doing so will play the animation exactly once. By duplicating model files and playing around with the global animation timer you can get some decent poses. Note that closing the program will reset the poses. Deleting models on the list above the one you just altered will also reset animations. Changing the animations too many times will also lock up the model. Spend some time getting familiar with the program, most experienced Spy'ers learn most of their tricks by just dicking around in the program. Best of luck with the poster.
