[Mono-winforms-list] [Mono-list] Bug? DataGridView on Mono Crashes (or locks rather)... does not occur on Microsoft platforms

[W Allan Edwards]

Yes, the DataGridView works now on 2.4 BUT I had a bug back on the 1.9 version where when I clicked on a tree node it would not select properly.  I then moved to 2.2  and that fixed that issue.  Now on 2.4 the tree node click issue is back! : - )
