I recently noticed that (with the most recent beta of WB), the GDI objects for wbload.exe really gets out of hand if I change my theme many times. I changed about 10 times the other day (yes, I am fickle) and noticed my system was running very slow. Opened Task Manager and wbload.exe had almost 10,000 GDI objects (normally less than 100). As long as I unload and then reload WB it gets back under control, and only seems to happen after many changes of themes. Just FYI.
