I can open the editor and use basically problem free. But in the R&D (research and development) window, when I edit the tech levels most work but at a few, like when using the R&D button under the Rocketry research area level 12, when I try to add the Intercontinental Ballistic Missle and the Multi Stage Ballistic Missle Test to my known applications it crashes out of the editor. Under the Naval tech it freezes up under a couple of applications. I have a HP Pavilion, 512 mb RAM, using a GForce 3 Ti 500 video card. Any suggestions? Thanks for any help
