Thanks for the information! Didn't have a linux box to test on and was just hoping it would work! Looks like our use of System.DateTime isn't supported on Linux (at least based on the exception).
Not sure yet about the screen size. Worked fine on Windows, I'll have to do a bit of research for Linux.
Thank you for at least giving it a shot! Not sure if I am allowed to upload a fix for our Linux build, I'll reply if I can fix it.
