Macro run by shortcut key malfunctions

If I run Sub pmOpenIt() from F5 key, fine. From alt-F8 and run, fine. I can even type call pmOpenIt() into debug window and run, fine.

But using its option-set Ctrl-Shift-Q causes it to run through the Workbooks.Open, and no further.

So that I can rule out corruption, can someone reproduce? It chokes in XL2003 and XL2007 here

Option Explicit
Sub pmOpenIt()
    Application.StatusBar = "running"
    Debug.Print "0 "
    Workbooks.Open "c:\delme.xls", 0
    Debug.Print "1 "
    Application.StatusBar = "Done."
End Sub
