5.0.13D User ID length

[Mustang65]

I copied my ISY994I setup to my ISY994ZW, and it went rather well, actually better than I anticipated reading some of the 5.x upgrade dilemmas. I successfully deleted the GEM appearances for the Energy monitor, but let's go back to the initial login. No 9 character problem in the 4.x versions. As requested,  I enter a 9 character User ID then a password and I get an error that the "User ID" is not long enough, character wise. I guess that there is a default of admin that is allowed in either field and that happens to be a lot less than 9 characters.
