In assembelies I need to label buildings and i'm using notes. Sometimes when I ctrl + z to undo, they all disappear. Sometimes when I hit escape, they all disappear, sometimes when I breath to heavily, they all disappear. I recenty opened an old project I was working on where I had to re-do the notes a zillion times cause they kept disappearing and bam, my screen was full of so many notes it made everything lag like crazy. Is it just Solidworks? Or is there some option that I need to have checked? I went into the annotations folder on the tree and selected every "visible" option.

Any help would be greatly appreciated.
