Howdy,

In catalogs, it is possible to open the preview using the "launch supporting document" command. I have been able to do this once so that I could keep the preview image open as I selected the component I required. In my later catalog creation attempts, I have been unable to launch the preview once I try to use the catalog I had just created.

I'm just learning how to create catalogs; so, I suspect the problem is how I have defined the preview.

Can someone please explain the proper process to me?

Oh, I thought they were the same thing. You know, "a rose by any other name..." and all that jazz.

Now that you explain it to me, I see a single "Document:" line at the botom of the catalog. I clicked in it and selected "Select". The I browsed to the image. This seems to have assigned the 'supporting document'.

Thanks for clearing that up for me.

On another note: when assigning previews for the components, themselves, I see three options: "local preview(stored in catalog)", "referenced document preview","external file preview" .

I know what the last one means. What do the first two mean and what are the pros/cons of each? I suspect storing it in the catalog will cause the catalog as a whole to open slower.
