+    Mac: Modify wxWidgets build script to fix a problem in wxMac-2.8.10 
+        which made the Manager extremely slow to update or respond to 
+        user input, by patching wxMac-2.8.10/src/mac/carbon/thread.cpp.
+        wxMac developer Stefan Csomor has checked my change into the 
+        wxWidgets 2.8 branch, so this should be fixed in wxMac-2.8.11.
