My Layout opening was really SLOOOOOOW. Of course there were stacks and stacks of older layouts that I've no idea why it's keeping.
So I went and clicked on the delete for each one. You can probably imagine what happened next.
It started deleting the list on the left side too. My precious SAVED layouts. Luckily I only have 3. Now I have 1.
And luckily due to a program bug in the new system, it was unable to delete my really big layout that was not loaded but it thought it was, so it refused to delete that one! Whew, thank goodness for program bugs.
So be careful on layout deletes: they don't protect your saved ones on the left side.
This was also true in Logos4 but the new system implies the saved ones are in a special status when in fact, they're no different than the junky ones.
Also remember when you're rescueng a layout from the right list (by clicking on it), remember you can easily hit the delete and that little puppy just got taken to the animal shelter. This is not hard to do with a touch screen.
