There's a polygon datased I need to clean before creating my map. It's not a big dataset, under 10 MB.
When I load my project, I can delete one polygon, or a group of polygons I have selected. A few times anyway. After a few edits, it just decides to stay in the "deleting selected features" forever. This happens even if I delete one by one. I tried saving edits, saving project, closing edit and saving project again between each deletion, but it doesn't work. I'm not working with any encumbering dataset in the project either. The only solution is nuking the whole application because it just won't respond. Ever.
Solved! Go to Solution.
Running into this today. Waited over an hour to just delete 86,000 records. Brand new map twice. I was able to calc a field in a few minutes.
Usually some of this caused by relates where a parent delete will go Null all the child keys on you - which it really should NOT do since it is a "unmanaged" relationship class.
