Multiplicity screen border driving me nuts

Hi,

I have just purchased the $39.00 version of Multiplicity. So far it is working.

However, at some point in the settings, I opted for a screen border and selected color yellow.

I know it some kind of indicator. Every time I move my mouse, the confounded border flashes on and off like I am at a carnival.

Now, I can't find any way to turn the option off in the settings.

This is extremely distracting.

Can you help me with this?

Thanks
