Why does object exist in Object Browser but not in test script while debugging

I'm debugging my test script, and break at a point where it checks if a window exists. I delay the script until the window exists:



  while(!Aliases["SwitcherProDT"]["WaitWinFormsObject"]("MainWnd", 0)["Exists"])

  {

      aqUtils["Delay"](500);       

  }



Its not finding "MainWnd" even after it comes up. So I pause the script at this point. In my watch list I add:



Aliases["SwitcherProDT"]["MainWnd"]["Exists"]



and it shows the value as False. I check the Object Browser and it shows Exists as True. At first I thought it was a mapping issue 'cause in the browser it has it listed as:



- Sys

  - ["Process"]("SwitcherProDT")

    -["Window"]("WindowsForms10.Window.8.app.0.33c0d9d", "SwitcherPro Desktop - TPS54611 6V to 0.9V @ 0.1A - 2188", 1)



But, the properties for this "Window" as the mapped name listed as Aliases["SwitcherProDT"]["MainWnd"].



So, why does the browser sees that it exists but the script doesn't?
