10.9.3 only lets me use 2 of my 3 30" displays

I have three 30" displays, but after the 10.9.3 update, only 2 of them work at a time. Is this a known issue? Can I downgrade to 10.9.2 to get the use of my other display back? It was working just fine on my Mac Pro with 10.9.2.

I have already received a response to the bug report from Apple, asking for more information. Good to see such a quick response. This is a pretty important issue for me, so hope they can fix it quickly.


Still, the more people who report it, the higher priority I expect they would give to it, and maybe be able to get different configuration information to enable them to track it down more quickly.

I came back into my office after taking a break to find my computer rebooting itself. I was upset because I knew the work I had arranged between my 5 monitors and 6 desktops would be in disarray. However I could not have imagined that I would find all of my work stuffed into one desktop and two monitors. Thank goodness for time machine back-up. I got everything back and into their appropriate spaces. Even though I was able to recover, it still cost me over two hours of valuable work time. I have blocked the app store and the update agent from being able to send or receive data in order to ensure nothing like that ever happens again. This is the type of thing that used to infuriate me about Windows and the primary reason I switched to Apple. My monitors are hooked up using Apple's active DVI adaptors per their connection instructions. This should not have happened.
