Hi. I've got one of the new Sony Z notebooks (specifically the VGN-Z11VN). These notebooks have a hybrid graphics system. They have a switch that changes between the integrated Mobile Intel Graphics Media Accelerator 4500MHD(part of the GM45 express chipset) and a NVIDIA GeForce 9300M GS. This change happens on the fly. When I use WB it initially works, but when I reset the computer (no matter which graphics mode I boot up in) the backgrounds of the windows and start menu are all completely translucent and unusuable. I've tried the last few versions, including the current 6.3. I am using Vista 32, 4GB ram.

I've currently uninstalled it. I would be interested to hear if anyone a Sony Z notebook with a similar experience or different. Thanks.
