One comment on “Intermountain Gas Bill
  1. I normally pay my bill through your website.

    However, I get a message to change Compatibility Mode to allow access since my version of Windows does not support the website.

    I did a search on “compatibility mode” and according to Microsoft changing the compatibility mode is done to allow an older program to run on a newer version of Windows which is the opposite of what you are suggesting.

    Your software people should set up a link from your website to the appropriate Microsoft website to allow us with lesser computer skills make to necessary changes without messing up our computers. Else, establish a method of using the old site.

    Please advise
