Hi Thorben,
This sounds like an issue that was taken care of in a maintenance release... can't remember how long ago. Sometimes the application would be minimized (for reasons we never figured out completely), and even on starting, would automatically minimize. This behavior should only occur with (1) older versions of Musician or Composer (the current version is 2.6.3) and (2) older OSs (operating systems) than Win 7. If you don't have the latest 2.6.3 version of Composer, you can visit the
Redownload Page to have your download link emailed to you.
If you have an OS previous to Win 7, and the problem still occurs, take a look at the task bar along the bottom of your screen. Do you see the Composer icon in the task bar after you've started it? If so, then
right-click it, and select "Maximise". That should bring Composer back up to full screen. (This trick works for any Windows application.)
Here's hoping...
