If there is more than about (I guess) 6 or so projects to convert from SC6 to SC7, those which are down the list will not be visible - making you think they are not available.
This will make many people think the SC7 has lost access to old SC6 projects. Basically it looks like conversion list screen needs a scroll bar (or bigger window). It would be also nice to be able to select a single project for conversion.
