apparently, there is something wrong with the shell icons in the
recent AS 2.51. Quite often AS will show some icon discrepancy
compared to explorer and other shells. It is not bothering me in
the most of cases but the Tortoise SVN subversion icons, where
file/folder icons are dynamically changing depending on the SVN
status. The SVN icons disappear in AS leaving standard windows
icons (even though Explorer and Co. are still displaying SVN icons).
Sometimes re-opening AS fixes the problem, sometimes not and
I have to go back to the f. windows explorer to do some SVN
work

Shows on both XP SP2 and SP3, not sure about Vista.
