    Photoshop CS6 x64 hang with switchable graphics (e.g. dock/undock)


      I'm running Photoshop CS6 x64 on a Lenovo T510 running Windows 7 x64.


      My Lenovo T510 laptop will automatically switch from Intel HD Graphics adapter (CS6 reports The Intel HD graphics card doesn't work with CS6's "Use Graphics Processor") when undocked to NVidia graphics adapter (CS6 reports as NVS 3100M/PCIe/SSE2) when docked. See http://www.thinkwiki.org/wiki/Switchable_Graphics


      Unfortunately, this means that undocking with CS6's default settings will hang Photoshop.exe with 100% of one CPU core. Photoshop recovers again after the PC is docked and the NVidia graphics adapter is enabled again.


      When I turn off CS6's hardware acceleration, the problem goes away.


      Help...Updates says I have the latest Photoshop CS6 installed.


      It's brand-new install and I haven't changed any settings since installation.


      This seems like a bug in Photoshop: PS should be smart enough to realize that the graphics card has changed instead of hanging the CPU.


      I'm posting both as help to other folks who encounter the problem, as well as to ask where I should report this bug to Adobe?
