I'm using Print Fix Pro on a Mac Pro running OSX and trying to profile 
an Epson 3800. When I get to the final step of printing my test target, 
I am unable to select semi gloss for the media setting in the printer 
setup screen. When I do, I get a weird dialog box(can't remember what 
it says)that when I click ok to close it, the paper type defaults back 
to luster. I able to select all other paper types without an issue, 
just not semi gloss. I would greatly appreciate some help on this.
