Hi, DP, Yes I tried re-installing but the same happens.
In Nero in order to browse folders on the PC you click "Browse" button , this opens a pop-up which should be in its expanded mode allowing me to open "My computer" and any drive and folder.
When the pop-up opens it is in a minimised mode on the main screen but the maximise button is "greyed" out. leaving only the minimise or close button active. If I click minimise it goes to the bottom task bar.
