When trying to copy "Standard 7941" to create a customized template I get - "Error No. -2146828282 (0x800a0006): Overflow" in a pop-up window. I can Insert templates based on other pre-supplied templates. But not one based on "Standard 7941" no matter how I try to configure it, or how I try to name it.
I think I know how this situation happened: When I initially tried to Insert the new template, I accidentally left the original name (Standard 7941)unchanged. CCM rightly gave me an error message, saying I need to give it a different name. But apparently the original got altered anyway, because when I go in to view "Standard 7941" it shows "Line" for button 1 and button 2, whereas the original (I think) was "Line" for button 1 and "None" or "Speed Dial" for button 2 (don't remember for sure because I never thought I'd need to remember).
