I am having trouble with a simple overlay in beamer. I basically would like to have a typical incremental slide series in a frame, in which embedded objects in one slide are not shown in consecutive slides. In my example I would like to show the contents of the columns in slide <1> only, then in slides <2-> just show the numbered items ("First enumerated item", "Second enumerated item", and their corresponding info).
I have tried several combinations of \only and specified the slides manually to no avail. I would appreciate very much any help.
Texmaker 3.2.2 on Windows
Best wishes and thanks!
