Selecting spot very slow after selecting tree node

[Robert Leach]

When I click a tree node, it takes 10-20 seconds for the selection in the grid to update. See attached image.

The problem seems intermittent. Sometimes it's slow, other times it is snappy.

It's the same DataTicker message update issue that I commented about in #59. Trivial to solve, hope I will find time tomorrow. The delay happens because TRView throws an exception and until you move your mouse outside the panel, the paint update in GlobalView (selection rectangle) won't happen.

If you make a "DataTicker crashes TRView paint method" issue you can close #59 again and assign this one as a duplicate.
