Export does not work in Ligthroom 6.14

[lvdorst]

When I select export no 'exporting' window anymore where I can choose destination disk and filename. 

When I press on the 'export' button than also Lightroom has been blocked.

By pressing the 'escape' button I can un-block the program. 

Re-installation has been done, but the same problem.

Can somebody help me to solve this problem ?

Do you have a second monitor that is not turned on? The export dialog might be there.

Or,  you might have accidentally dragged it completely off screen.

In that case, resetting the preferences should fix it.

Thank you very much.

The exporting window was on my second screen.
