Anyone else's Logitech G5 middle mouse button a PITA?

[Participant]

Love this mouse so far, but the middle mouse button is tricky. When pressing it it's pretty stiff, and it's easy to press the scrolling function instead.

Has anyone else found this or do I need to RMA?

A tip for you - install the logitech software, then bind the left scroll (i.e. tilt left on mousewheel) to middle click. It becomes much easier to use, because you need to apply only a small amount of pressure to middle click.

Thanks for the tip, but what does one then use for left scroll? I use this feature on the web and in Excel quite a lot.
