HOW DO I GET THE NAME OF THE COMPOSER FLUSH RIGHT?

1. Click on the name
2. Turn of caps lock (or get your keyboard fixed)
3. Open the Inspector (F8) if it isn't already
4. Set the text to right align.

Assuming you typed the composer name into the dialog when you created the score, or else added it via Add / Text / Composer, it should already be flush right. If it isn't, then you must have added it using a different method. probably best to delete it then add it correctly. It's also somehow possible just changing the alignment will fix it as suggested above, but that totally depends on how it got messed up to begin with. If you need further assistance, please attach your score so we can understand and assist better.
