This is fairly similar to the problem I'm having, I run AC3D on my laptop and because the windows do not scale to the resolution, the lower half of the panels are often cut off.

So perhaps adding a window slider to the lower left panels would work, also because of this I cannot access the buttons for unwrapping.
