I have a problem with the keyword StatusMessage: the Position parameter is not working.
   
    StatusMessage Title="Start..." Position=(20,20)
    StatusMessage AddString="Please wai

Yes, this is currently a shortcoming in GuiXT. Workaround: Please put the first "AddString" into the first StatusMessage command:

   StatusMessage Title=... Position=... AddString=...

The "position" option is not effective without the "addstring" option.
