Wenn man die Taskleiste auf "Automatisch Anzeigen" einstellt, erscheint sie automatich mit einem kurzen, kaum sichtbarem weissen rechteck. Dann fährt sie wieder runter.
AmIcoSinglun ist mit Sicherheit veraltet. Die letzte News bei dieser Firma stammt aus dem Jahre 2009. Jetzt ist es eher fraglich, das eine solche Software frei von Bugs ist. Gerade wenn es um die Verwaltung von Speichermedien geht.
