This might be a shoot in the dark, but I have experienced some problems with wxwidget 3.0.2 when I compiled and used the debug version of wxWidget. One thing is that the preview window got all black (similar to your first screen shoot)
PS
I compiled wxWidget like this
../../configure --enable-unicode --enable-debug --enable-debug_info --enable-debug_gdb
