Telescopic Bomb sight on Ju88 not working?

[dflion]

I'm currently updating all my campaigns in COD and am currently working on my III.KG1 Ju88 Campaign.
When I go to use the telescopic bomb sight after going to the bomb aimer position then pressing SHIFT F1 (Controls/view/Lean to Gunsight) I get a 'black screen' and my computer 'crashes'??!!
The command SHIFT F1 works ok in the fighter cockpits - to move you closer to your gunsight.
I think there is some major glich here. I would be grateful to hear if anybody else has experienced the same problem and whether there is a fix for it?
