Slow load and selection problems in Windows 10
As of the 5/16/17 update, trying to select objects right after the file opens causes the app to freeze or slow down dramatically for almost a minute. If you try to select a different object or deselect it doesn't do anything and then it looks like it struggles to catch up. This was not the case in the previous version.
