I think this is not reported, at least I didn't found it...
I am using the default find and replace dialog and with the following steps I get an exception:
- Insert text in the find combo box
- Change to replace tab
- Click on replace next
The exception occurs in FindReplaceDialog.cs, in the function AddReplacMru.
cboReplace.SelectedIndex = 0;
As the combo has no entries it is not possible to set the selected item.
I solved it by checking the combo box entries.
