Options dialog changes to unrelated page on error

1. From the "Qt VS Tools" menu, select "Qt Versions".
2. Click on the "+" icon.
3. In the "Path" column of the new, still empty line, type or paste the path to a Qt version.
   Do not use the "Browse" button and do not provide further information.
4. Click "OK".
   You'll see an error message that the new Qt version is invalid because it doesn't have a name.
5. Accept that error message with "OK".
   The Options dialog shows the general Qt settings.

It would be more helpful to stay with the Qt versions, so users can correct their mistake.
