Specifically, because it hard-codes English strings when looking for sub-controls and control types, such as "Open" and "list_item". These captions are localized on other OS's... i.e. on Spanish these captions are "Abrir" and "elemento de listo," respectively. Here is the diff of how I fixed it. Replaced "Open" with "*" since there should only be one button-type control as a child of a combobox. Also replaced "list_item" with the ControlType.ListItem property. I had to add the element's control type to the propertyHT in Utils.cs at the bottom.

This is just the first issue I encountered running one of our tests in localized OS. I imagine there are many other hard-coded strings in LDTP.
