So SetSelectionMode breaks the reporting functions; a bug yes?

The LabelSize functions have no negative effect on the GetSelection
functions. Why did you wish them commented out? Is it that
GetSelectedRows() will only return the rows that are selected by
clicking on the row label?

Good grief this means I have to merge all the answers from *all* the selection
functions! At a minimum the docs need to point out all the conditions that cause
these functions to return anything. Having a function that did all this house
keeping inside of the Grid Ctrl would be a nice improvement.

It could be, but there may be some rational for it that I don't know about.

The LabelSize functions have no negative effect on the GetSelection
functions. Why did you wish them commented out? Is it that

Yes.
