I’ve had Audacity on my Macbook Pro OSX 10.8.1 for 6 or 7 months and it has worked fine up until this week. Now when I start up the programme, there is no default blank edit window, and if I try to open a project or import an audio file nothing changes and no edit window appears. All of the options in the File/Edit/View/Transport bar at the top are available but have no effect when selected.
I have tried deleting and reinstalling Audacity several times but it hasn’t solved the problem. When this first started I happened to have Logic Pro open at the same time, though it happens whether or not I have concurrent programmes running.
