I'm converting all my 9.3.1 python scripts to 10.0 sp1 arcpy scripts and getting fatal crashes in IDLE when I use the r raw string when defining constants which worked fine in the 9.3.1 gp.

Layers = r'Road Centerline'
Scales = r'2000;900'
All = r'Recreate All Tiles'

arcpy.ManageMapServerCacheTiles_server("server","BaseCache/RoadCache", "Layers", Layers, Scales, All.......etc)

After I changed the constants to replace r with " it worked
Layers = "'Road Centerline'"
Scales = "'2000;900'"
All = "'Recreate All Tiles'"

I've used r for years with python and had no problems in the past.  It was a habit and am now having to change all references of r when used in an arcpy call.  The r still works with python functions such as open(r'C:\GIS Scripts\RoadCacheLog.txt', 'a')

Has arcpy been designed not to accept the r now?  because it worked with gp!
