Oh. It needs a double click. Did'nt thougt about that. After 19 years with windows i just noticed at this moment and now the explorer just needs one. Astonishing ;-). I will change this.

Edit: That's funny. These explorer list items within programs always seem to need 2*Click (or a middle mouse), wereas the windows explorer needs only one. Never noticed that. Strange. Seems to be unchangeable.
