Re: tank colours
Soulza 
understands.
I am using a PC with mega credentials that was installed. Sadly I cannot work the PC and am limited ONLY to what I can do with it.
Perhaps it is the settings but I must allow Soulza the opportunity to at least fix this for me. Henceforth I am changing my settings.
To all and everyone that has tried to assist. I will let you know the results.
Soulza, MY settings are as you describe above and can easily run this game standing on one finger so what else can I change?
