Prevent error dialog when the cursor has disappeared whilst displaying
a popup `tip', as can happen when running x11/unclutter and leave the
mouse over an item with a tip; the tip is displayed, the mouse hides,
and now pck-timer doesn't barf when the mouse reappears.
Fix from Ben Elliston, who knows much more tcl than I do.
