I am working on an application that uses the a ListView. This particular
app needs to be able to handle more then 32K items in the list. A solution
would be to change the boundries in GridView from short to long. This
approach will disable the selecting using regions. Does anybody know of
a better solution?

The best answer is probably "roll your own".  If all you need is a list,
with constant row heights, this probably won't be too hard.  And it will
probably be easier in the long run than all the hacks you'll have to make
to get TGridView to work.  The only tricky part will probably be
remembering which items in the list are selected.  Perhaps you could do
this with some sort of array or linked list of (start,end) selection
ranges.
