--- Comment #3 from Roy Shea royshea@gmail.com 2008-09-03 19:50:50 --- The calls to Patch in RichWindow::RichWindow (located in rich_window.cpp of attachment 15812) are failing. This causes the intercepted versions of BeginPaint and EndPaint to not be called. Thus, the device context setup by RichWindow::OnPaint is not correctly updated.
The call to Patch fails with ERROR_GEN_FAILURE, indicating that the problem stems from InterceptEnumCallbac (located in base/iat_patch.cc). Unless someone beats me to it, I'll narrow down the test tomorrow.
