Working with thousands of objects, which happen to be rhinestones, the document will not close when the x box it clicked.
Along with this problem, the Object Properties dialog totally goes bonkers, opening some sub trees, and the scrolling action goes haywire.
Note: THOUSANDS of objects, as in rhinestone fills.
This machine has plenty or ram, plenty of cpu.
If you want to share a file, one good way to do so is to put it somewhere on-line (e.g., Google Drive, Dropbox, WeTransfer) and then post a link to it.
