"Preparing to export" window hangs after completion when multiple export presets are selected

[RomanP]

When I select multiple export presets in the Export dialog, after LrC finishes exports, the window "Preparing to export" still hangs. I then need to close it manually. This doesn't happen when exporting only using one export preset selected.
