Line 119 of the Data Grid button script is (edit script of btn "Data  
Grid" of stack "revDataGridLibrary":

put queryregistry("HKEY_CURRENT_USER\Control Panel\Colors 
\HilightText") into sSystemA["hilited text color"]

My guess is the revLet doesn't like to have the registry queried.

You can probably update the switch statement in the _Initialize  
handler with following. I'm just wrapping the queryRegistry calls with  
a check to see if the code is running in the browser:

  switch the platform
             case "Win32"
                 if the environment is not "browser" then
                     put queryregistry("HKEY_CURRENT_USER\Control Panel 
\Colors\HilightText") into sSystemA["hilited text color"]
                     if sSystemA["hilited text color"] is not empty then
                         replace space with comma in sSystemA["hilited  
text color"]
                     end if
                     put queryregistry("HKEY_CURRENT_USER\Control Panel 
\Desktop\WindowMetrics\ScollWidth") into theValue
                     if theValue is an integer then
                         put abs(theValue/15) into  
sSystemA["scrollbarWidth"]
                     end if
                 end if

                 break
         end switch
