Hi Tim,

oops, my mistake. I just re-tried it. No difference in behavior. I could be wrong but I thought "Path" was just the default parameter and specifying it was optional.

I swear it was not doing this before. It wouldn't display a thing unless I forced a value into the SelectedIndex. Nevertheless, It seems like it's almost working correctly now. I just need the combobox to display the correct value upon first view of the window.
