I'm running Ubuntu Breezy Badger with Gimp 2.2.8 and stitch panorama 0_9.6.
I choose stitch panorama and select my images. I then choose to set/edit/view control points. I select areas and choose add. I add points without problems. After adding the points, I click on Accept.
The window closes and returns to the main stitch panorama window. All buttons on that window are disabled and I can't proceed to perform the stitching. I've let it fo for a while and nothing appears to be happening.
