I get this error message, from time to time:

500 Internal Server Error
"Script Error
Error:command: Response.Redirect("Scheduler.a5w?Scheduler_filter="+filter)
Member property does not exist
Response.headers[] subelement not found."

in various places, where only the 3rd line will vary depending on where in the application it occurs. Using the brwoser back button, then resubmitting usually allows me to proceed.

Does anyone know why this error occurs?
