Could someone please help me problem solve this?

For my settings, I'm using an Intermediate board size since it fills the screen quite nicely.

Okay, so when using Microb in full screen, there's like some type of offset. I have to click two squares to the left from the chess piece I'm selecting.

If I'm in windowed mode, the offset is one square.

Is there anything in the about:config options that can be changed to resolve this?

I would use Tear, but for some reason, it doesn't save the cookies correctly.

Super many thanks if someone does actually take a look at this for me.
