Hi Sergey,

This code wouldn't run for me -- the debugger complained that RVData had

no method SetSelectionBounds.

I eventually found that I needed to cast the RVData like this:

TCustomRVFormattedData(RVData).SetSelectionBounds...

It still doesn't seem to be selecting and deleting the text, though. I'm

still working on it.

Cheers,

Martin
