I am flying the F-15C with the easy radar. In this mode, I press the 2 key to bring up the LRS radar, however, I can only fire the AIM 120 missile in the Visual mode. I can lock onto a target, however, I don't get the Target designator, range scale or steering dot. Nor do a get the shoot que. Is there a way to get this in the easy radar mode?

I recenty upgraded to Lock On 1.1 (Flaming Cliffs and patch 1.12a). I now have some chopiness so I changed to low graphics. It was better but I got some flashes and bounced back to Windows. I also just upgraded to the latest Nvidia 93.71 driver. Could that be a problem or do I need to upgrade? Here is my system: OS: Windows XP, CPU: Intel DualCore 6300 1.86 GHz; Memory: I GHz DDR RAM; Display: Nvidia GeForce Fx 5200 w/ 256 MB; Motherboard: ECS P4M800Pro-M. Is it worth trying a better video card and/or more memory before upgrading CPU? Should the CPU be OK?
