Last night I noticed Boinc was not up and running. I clicked on the manager and nothing happened. Below is what is repeated numerous times in the error log.

CPU: Intel Core 2 Quad Q9550
GPU: AMD/ATI RV730 Pro [Radeon HE 4650]

(boincmgr:18217): Gdk-ERROR **: 20:39:26.603: The program 'boincmgr' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 8644945 error_code 3 request_code 18 (core protocol) minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
