Thank you for this thread. I too find the select button on my MX700 a bit hard to press and have made the info button above it the select button. Has worked well for 10 years and now the lines on the screen are fading fast so it is time to replace my dear MX700. Amazon has the MX850 at a reasonable price but doesn't mention the software.

Question: My MX-editor (for the 700) no longer updates. Where do I get the MX-850 editor?

Thanks again
David
