I have an unbound DataGridView. Previously I was able to select the row header and press the Delete key to delete the row. This no longer works. I don't know when it stopped working. I have 'AllowUserToDeleteRows' set to True. The entire row is selected and pressing the Delete key erases...

The 'Hot' key shortcuts on all menus and buttons do not appear until after I press the ALT key. I may have a text property of E&xit on a menu or button. It shows as Exit, but the 'x' is not underscored until after I press the ALT key. This seems to be a very basic requirement. I'm sure there...
