[TenTec] Urgent OMNI VII Question

Has anyone ever had to re-boot their Windows based computer for any reason? 
And when installing or doing a software update, has the computer required a 
re-start?  I view the same will likely apply to most any firmware based 
radio.

Yes one will need to reload their personal frequencies and re-set the 
personal MENU items after a Master Reset.  However by using OnePlug and 
having the computer connected to their router they can down load and upload 
the personal frequencies.

Are we really that frugal?

Bob, K4TAX.
