Save errors when using grid view

Save errors when using grid view

When attempting to edit a record from the grid view, once I click save, I get a pop up window that reads, "1 record(s) could not be updated. Show Details"

When I click on the "show details" link, the pop up window expands slightly, but no details are provided.

When I use the summary view, and select "edit," I can save changes without receiving an error.  

This bug slows down data cleanup/data entry considerably and needs to be fixed! Also, I'm getting the same date problems that other users have complained of.

My application is shared with support . . .
