Yep ok, sounds like it's Primo itself not Windows, and I imagine it's one of the .ui files the function is in.
I guess it'll have to be found and commented out to stop it.

Perhaps try searching navigatemap.ui for <BUTTON screen_captt or maybe <BUTTON screen_captt class=txt_20 or maybe even some more of that line I commented out above, to see if you find anything that might be it.
