Hi Joe,
With content in the right column, the "Show Page Right Content In All Views" option enabled, and a page menu in the left column but no content in the left column, clicking any of the views hides the left column. Enabling "Show Page Left Content in All Views" doesn't help. The left column (with menu) shows up in all views when "Show Page Right Content in All Views" is disabled. If there is content in the left column and the "Show Page Left Content in All Views" is enabled, everything works properly.
I reproduced this on the demo site.
Thanks,
Joe D.
