help with putting a mix i've done onto BOA

[TechMouse]

but everytime i was mixing , the pc would go on to the screensaver, and make some crap windows noise

Turn the screensaver off when you're recording mixes?

i know this might sound dumb, but how do you do that ??
where is the option to do that?

Right click anywhere on your desktop.

Properties.

Screen Saver tab.

Select "(none)" in the dropdown.

Alternatively, set 2 or 3 hours in the "Wait" box.
