Hi Brad, One of our users here had experienced a similar occurrence of components being hidden just this morning. A forum search found your post and another of our users also found a solution in the interim.
There is a setting in tools>options>systems options tab under the drawings page called "Automatically hide components on view creation". This was checked on the machine the user who experienced this behaviour was using. Unchecking this option returned the components on the drawing views.
I know this is nearly 2 years after your post, but maybe it will help someone else with a similar issue.
