Installed the 2.6 trial version of Notation Composer on Vista. It operates too slowly to even play with. Simply switching between windows causes a 20 second delay in which nothing can be accessed. It displays "Not responding" in the title bar. Running the Wizard to create a new song takes about 15 seconds a screen.

After initial install, several errors about directories not being there. Found a KB article that walked us through creating the directories, but now operates too slowly.

Any ideas?
