I generally get called on to projects to do custom module development and internal architecture/engineering, so I have increasingly less frequent contact with the front end tools and site building type modules. But I've been playing with Panels again lately for a project and ran into an issue with block visibility. While Panels will generally give you an option to respect a block's configured visibility settings, for blocks generated via Views, it does not (even if you have specified visibility rules for that block via admin/build/block). I suspect this is because Panels invokes Views generated blocks directly thereby bypassing that extra 'layer'.
Read on for one solution to this problem.
