    Hi everyone

    I have posted this at a few apple forums and not had any responses. This issue is driving me mad. Hopefully someone here can comment on this unusual behavior...

    I am having an issue with my 2011 MBP. I have it plugged into an Samsung monitor, mirroring the MBP screen and using clam shell mode.

    When I wake the MBP, sometimes i get the blue flicker screen (as if its trying to get the resolution right or something), and then a black screen rather than the desktop showing.

    After i unplug my HDMI cable and put it back in, or turn the monitor off/on again, the desktop usually, but not always, shows on my screen as normal. The weird thing is, my opened windows such as firefox, transmission, or itunes have been moved across to the right hand side of the screen and I can only see parts of them...and the window size has been adjusted or shrunken.

    Has anyone ever had this issue? is it a Mountain Lion bug?

    I will link to a screenshot below – you can see firefox on the far right near my HD icons.

    I am new to Mac, however, on my new MBP and my Windows PC's, I NEVER put my computer to Sleep.

    I am using it or it is OFF. On my Sony, I have a button, to turn off the screen, which I do routinely, but never sleep. ALways seems to cause problems.

    Haven't found the screen off function yet, although I did see an option in the screen saver where you can program a corner to turn off screen. Not sure if it just turns off screen or puts the computer to sleep

    I also never put my rMBP to sleep while connected to my external monitors. I make sure to disconnect the monitors before the power since it will go to sleep in clam shell mode as soon as the power is disconnected. When I did it the the other way, it wasn't uncommon for me to open the lid and have it wake up to a trashed screen that needed a reboot to fix.

    Excep for an occasional annoying bug, I've never had a problem with sleeping my Macs(unless I had a RAM issue). My MBP was up for over a month without shutting down or restarting, I'd just close it up when it wasn't in use and let it sleep.

    I reset the pram, and nothing has changed. I'm still having the issue.

    I did attempt to reset the SMC - how do i know if it has worked? there were no beeps or anything when i did it.

    I am starting to think I should just go back to using VGA because there was never a problem when i was using that connection.

    I have my mbp in a bookarc stand and like the fact that it saves space, so I don't really want to have my mbp open all the time...

    I am so upset about this. I wish i could find a fix.
