Hi Jakub,
You seem to have hit the nail on the head regarding the config.pro option. It is interesting however that setting interface_quality to 0, 2, or 3 does not resolve the issue whilst setting it to 1 does. Is this option only for plotting purposes? If so I am working exclusively from pdf documents and I presume I could set it to 1 permanently and not worry about generating any mapkey.
Otherwise, I am working on Creo Parametric 2.0 build M100 and would like to learn more about utilizing a mapkey and possibly iconizing it. In spite of working on Creo for about a year and a half now, I had never heard of mapkeys and upon doing some research found the following helpful links:

I will do some more research and potentially utilize this functionality in the future.
Thanks for the help!!!
