      Description

      **obscure**

      Import a PDB file (3WV) and make sure that both temperature factor and secondary structure annotation are shown.

      Open the find window and put in a simple regex (e.g. 'st+'). Hit find a few times.

      Click in the alignment frame and create a new view. Don't adjust the window size - the annotation panel height is incorrectly set so that no sequences are visible.

      Now hit the 'Find' button again - NPEs appear on the console:
