When I'm in the batch area, entering cabinets, I click on the 'view' tab, and select 'collapsed'. The thumbnails collapse as they should. When I go from there to the cabinet editor, then back to batch, the list has gone back to thumbnails.
There seems to be some kind of conflict happening between areas that is reverting this setting back. I will add it to the list to be looked at. For now, if you change it to collapsed (or whatever you are wanting at the time) and then shut down eCabinet Systems and restart, it will hold on to the choice you made between areas.
