[Mobhack]

Not seen in my copy of Mobhack - running Windows 10.

At least - if that is Cuba - cant read the pixillated photo even if I put my reading glasses on!

Read the Mobhack help on "TransparentColour" - use your browser's search function to find that. It's from the old days when apparently some monitors did not work with the colour, depending on the Windows colour palette chosen. Or if in 16-bit colour mode, choose 32 bit high colour.

But it will only be a problem if all the shapes in Mobhack are showing a similar grey background!. If it is just that shape, something is up with it alone - for your particular monitor settings.
