"If I download Screenshot Utility. Can it cause any problem with P3D software?"

No, works with all programs .. but you have to use a key that is not used by your programs ... otherwise, select another key.

 

I have used it for years ... no problems .. I set up the F8 key (but you can use what you like).

 

It shoots a jpg of whatever is on your main monitor screen then puts the jpg in your ... selected folder.

 

It makes screenshots as fast as you can press the selected key ... it gives a "shutter sound" when it takes the photo.

My overland models have no working lights, what's the best way to fix this issue?
