X and Fluxbox :: screensaver has stopped working

hey, i was trying to figure out how to change the ss with beforelight, but now my computer doesn't go to ss at all.

Code Sample

X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 113 (X_KillClient)
Value in failed request: 0x1e00001
Serial number of failed request: 12
Current serial number in output stream: 14

i get that error when i do 'beforelight' at the prompt. what can i do?

does anyone know how to configure beforelight??

is beforelight really that mysterious??
