TuneUp 25 - JAWS checks

1. Open TuneUp. Confirm the startup trumpet (if F3 introduction is enabled). Close and confirm TuneUp says "Exiting TuneUp!" with no closing trumpet.
2. Play music. Alt+Down and Alt+Up should change only the music volume, without spoken key names or percentages. If old JAWS key labels persist, switch away and back or restart JAWS once.
3. Press a command while a previous TuneUp message is still speaking. The old message should stop, and the new result should be heard. Try arrows in F1/F2 and typing a playlist name too.
4. Select the desired playlist with F2 or Ctrl+T. Insert a blank CD-R/CD-RW and press B. Arrow through the writer list; Enter selects; Escape cancels. Confirm that the Yes/No burn prompt defaults to No. Choose Yes to test an actual burn. Wait for the completion message, then play the CD in a CD player.
5. Try a playlist longer than the CD can hold. Expect: There is not enough room on this CD to complete this task. Remove some files and try again. Press Enter on OK. Confirm you returned to the same playlist, with songs and files unchanged.
6. Try B with an empty playlist, no writer, no disc, a used disc, and an unavailable song. Expect an accessible explanation and no playlist changes.
7. Verify S Stop, End last song, selection and M, A, E/R confirmation, shuffle, and the five main buttons in their established Tab order.

Validation limits: automated tests cover native accessible controls, audio preparation, exact-fit and insufficient-capacity writer simulations, speech queue interruption, quiet volume, and preserving JAWS settings. The development environment reports zero optical recorders. A real CD burn and live JAWS speech/key-echo behavior still need your hardware test.

Version 25 playback checks:
1. Press 1. Confirm Shuffle is off and the first alphabetical song starts. Let it finish: the second song should start automatically. Playback should stop after the final song.
2. During playback, Tab to Shuffle and press Space. Confirm Shuffle on is announced and the current song continues without interruption. The next song should follow the new shuffled order.
3. Press P. Confirm Shuffle turns off and the current song restarts. A number key instead starts that numbered song in alphabetical order.
4. Space pauses; pressing Space again resumes the current song with Shuffle off. S stops playback and it must stay stopped.
