Help please: Refreshing a window

Question

Hello,
I would like to refresh a window so I have
try
tell application "Finder" to update folder "My folder" of desktop
end try
It compiles but does not work, I have to do this:
try
tell application "Finder" to close folder "My folder" of desktop
tell application "Finder" to open folder "My folder" of desktop
end try
That compiles and works, but the opening and closing of "My folder" is obvious to the user.
How could I improve that?
Thanks.

Lennox, you could try using this free shell utility. It has worked just fine for me. Here is the link:
http://osxutils.sourceforge.net/
The man page you want is "/usr/local/bin/wsupdate" if you don't specify a file then the finder windows should be updated. Here is a example of using this shell command.
set Icon_From to choose file with prompt "Choose the file you want to copy the icon from?" without invisibles
set Icon_To to choose file with prompt "Choose the file you want to copy the icon to?" without invisibles
my ReplaceIcon(IconFrom, Icon_To)
on ReplaceIcon(FromFile, To_File)
try
do shell script "/usr/local/bin/seticon" & space & (quoted form of (POSIX path of From_File)) & space & (quoted form of (POSIX path of To_File))
try
do shell script "/usr/local/bin/wsupdate" & space & (quoted form of (POSIX path of To_File))
on error Error_Message
display dialog Error_Message giving up after 2
return false
end try
on error Error_Message
display dialog "Requires osxutils from http://osxutils.sourceforge.net/" giving up after 3
return false
end try
end Replace_Icon
