Summary0000338: Crash in Viewer
Description

Viewing a comic image strip within Viewer and then closing the viewer and viewing another image strip causes a Null Reference exception.

This appears to happen because the Viewer form has been Disposed. Not sure what introduced this bug as it has been working perfectly fine all this time.

Seems to just happen on the following line, despite all controls having their .Enabled states set directly before this line.

Me.tbrMain_ZoomLevel.Enabled = gotImage

Steps To Reproduce
  1. View any comic strip's image in the Viewer.
  2. Close the Viewer.
  3. View another comic strip's image (the same comic or a different one) in the Viewer.
  4. Observe nullref exception.

Seems to happen when the second image is downloaded as opposed to being loaded from the on-disk archival cache.

Updated to use Common.Panels.IsViewerOpen instead of doing a direct check of the pane/form.
