I think that the problem is that win32lib does not try to automatically
reselect the currently selected item after the list has been resorted. I'll
try to see if this can be done without too much effort.

Remember that what is being selected is not the item itself, but the row
that the item appears in. I'm not sure how this effects non REPORT-MODE
lists.
