See if TRY...ENDTRY could help.

>Have been using xmlhttp to get shipping rates from UPS. Now want to detect case where client is not connected to internet so can handle gracefully. If disconnect from Internet and run program, get error 0 at lcxml =oxmlhttp.responsetext statement below. Tried to intercept with on error, but success seems to depend on whether am in debugger or not.
