Hello, Ludek.
Here's an example of changes we make to the file: open in VS, change text or layout of text objects, then click the save icon. VS does not appear to save the file initially after clicking the icon. We would go to click the icon a second time, then that's when the crash occurs. The database is an ADO.NET connection to a local XSD file. We do have "Verify On First Refresh" selected in the database options, also.
I'll try SP 16 to see if it will remedy this issue, and reply with the results.
Thanks, Ludek!
