Can't press more than 2 directional arrows keys at the same time

I just noticed that in the Macbook Pro Retina that I bought recently there's no way to press more than 2 arrow keys at the same time, or at least the system does not seem to handle it.
All other keys can be pressed at the same time without any problems, so I think that the problem affects only the arrow keys.
I'm surprised that in a modern computer can exist this type of limitation
I think Apple should update the system to allow this - car gamers like me will thanks or feel less disappointed...
Any help would be appreciated!
Thanks

Uninstalled everything PA, also uninstalled mangler which was the only thing that depended on PA. It didn't work anyway.
No pulseaudio --kill command so I couldn't run.
Checked systemd journal and there is no mention of PA this time.
Checked top, and grepped ps aux and there is no PA there either.
I also rebooted the machine completely just to make sure. However VLC and HTML5 have the same incompatibilities.

I see. That's too bad. At least we're not alone.

As long as the profiles are different (ex. HID vs AD2P) you will not have any issues. But say if you try to use 2 keyboards at once, it won't work. Or 2 headsets at once. Your scenario seems fine.

Can we start more than one user created database at the same time

Hi.,
Can we start/work more than one user created database at the same time ??

Hi Shyam,
I really dont understand what you have asked?
If your question is can we start more than one database at the same time then the answer to that is yes but provided to have enough resources on your server to support running of two or more different databases on the same machine.

Can takes from more than one track be comped at the same time?

Greetings,
I know that this question has been asked recently in this forum (http://discussions.apple.com/thread.jspa?messageID=9527542&#9527542), but I don't think that the respondents completely understood the question... Or perhaps I did not understand the suggested solutions to the problem. I will ask the question in a slightly different way...
Suppose that I record guitar with 2 microphones (a pickup mic, and a room mic). The first microphone is recorded onto track 1, the second microphone is recorded onto track 2. Multiple takes are done in this manner. When it comes time to comp the tracks, how is it done? Can the takes from more than one track be comped together at the same time? I have tried to do this by grouping both tracks together, but it does not work.
Any suggestions?
Thank you.

You had the right idea grouping the tracks together. You must make sure that in the group settings, the box titled "region selection (edit)" is checked. This will allow you to make the same cuts (or in this case, swipes) on all regions in the group.

Can you have more than 3 Bluetooth devices active at the same time?

I have trouble getting my Sony DR-BT101 to link when my mouse, trackpad, and keyboard (all wireless) are connected. I need to link by stereo headphones for music analysis and cannot get all to work at the same time. My Sony headset either won't pair or connect or causes alert that interfere with the running of other programs during my work. Even when I answer one of the alerts and turn off the Mouse it refuses to connect and finishes with a Stop Using Headset message. Even if I choose "Ignore" instead of turning off the Mouse or Trackpad, same thing. I once had everything working at the same time, so I can't figure out what is going on but it won't honor more than 3 devices, it seems. And also, when a new email arrives in my mailbox (iMac OS Lion 7.1 Mail), the alerts stop popping up and go through 3 iterations as each new email arrives. Weird. Any response on how to deal with this?

Can't have more than one application watch videos at the same time

The title isn't entirely accurate. I will write all my observations here.
I believe I started to notice these problems since the (recent) X11 update which seems to have happened in July. The subsequent Mesa updates may be related. These updates also caused X11 to crash sometimes, this issue got resolved after a patch update though, it seems.
Before I share my issues I have a Dell Vostro 1500 with the Intel Core 2 Duo processor (which includes the integrated GPU), using the Linux BFS 3.16.6-2-x86_64 kernel (plan to upgrade tomorrow morning while the internet is quick) and the packages listed in https://wiki.archlinux.org/index.php/Intel_Graphics.
The most reproducible version of this problem I've had has to do with Chromium, VLC/MPlayer/MPV and to an extent Firefox.
To reproduce all I have to do is have Chromium open and watch some video on YouTube (HTML5 as I do not have version with Flash included). Then I open a video in VLC/MPlayer/MPV and one of two things can happen:
It can work on VLC, but then if I go back to the HTML5 video when I press play it tells me it has crashed and I should reload the tab.
VLC simply does not work and it plays the audio but no video, sometimes not even the audio.
This is VLC's output in a case where nor the audio or video work (and the HTML5 crashed as well):
https://imgur.com/J897mMG,17xu7ip (album of 2 scrots)
I had to close VLC for the HTML5 to work, and if you're curious, yes I am listening to Weird Al as I write this. Most of the time I have to reset X11 (or even reboot) to be able to watch videos or listen to audio with VLC again. I have noticed that sometimes if I haven't watched a video for a long time VLC works again (or at least the audio does, sometimes the video).
OK so that's with video apps. This may be unrelated but I think it's worth mentioning here. With Firefox I run into an issue where Flash gets super glitchy, it gets stuck in one glitchy frame or it flashes between two glitchy frames, sometimes it shows the video in the background with the glitchy frames on top still flashing (so I get glimpses of the video), and other glitches.
Some of the ways I fix it are to reload the tab, open a new Firefox window and open the video there, reset Firefox, close Chromium's video tabs, amongst others. None of these work 100% of the time. Sometimes none of them work.
That is all that I can think of. I've been doing a couple of weeks of tests and normal usage in order to acquire this report so it'd be cool if there's a solution.
Thanks! If there are any questions or further information you need, feel free to ask.

HT4314 Can I have more than one Game Center account on the same Apple ID? If so, how do I set it up?

I am playing Clash of Clans on my iphone and on my iPad. I would like to connect each of my games to a different Game Center ID so I don't lose them if something happens to my device, but I can't figure out how to do that without creating new Apple IDs for each device and I don't want to do that. Any advice? Can I have more than one Game Center account under the same Apple ID? If so, how do I set it up? Thanks!

If you use the same account see the following to separate Messages and FaceTime between the two iPod see:

Three or four arrow keys at the same time required.

I sometimes play a browser game that is much like the dancing game, and it sometimes requires me to press 3 or 4 arrow keys at the same time. It does not seem to detect when a third or fourth arrow key is being pressed, in any application. Is there anything I can do about that?

Is the problem the way the keyboard was built, or is there some kind of setting I can change, or is there some kind of program I can download from somewhere that would fix my problem?

Can I update more than one iPad and iPhone from the same MacBook pro?

Can I update more than one iPad and iPhone to ios 5 from the same MacBook pro? Our family has one MacBook pro and several iphones and ipads. No one wants to lose their iTunes music or contact list or calendars.

Yes, but you will want to think it through before you do it.
The computer will become the "master" device, holding the definitive collection of music, photos, contacts, etc., and each iPad or iPhone will get a copy of what's on the computer. So if everyone has different collections of music or photos that you all want to keep separate from each other, you'll want to set up different accounts on the MacBook Pro. To do that, go into "System Preferences" and click "Users", then click the "+" to create a new account for each person who needs their own set of files.
That way you can each log in to your own MacBook account before you sync your iPhone or iPad, and everyone has their own copy of iTunes and their own iPhoto. If you happen to plug in an iPhone while logged into someone else's account, you just click "don't sync" (the 1st time only, it will remember after that). Sharing the same files becomes tricky, so this is only the best method if you want to keep things 100% separate.
On the other hand, if you all have your music and photos mishmashed together on the MacBook anyway or just don't care about keeping things separate, just go ahead and sync your iPhones and iPads without setting up new accounts. But in this case, you should create playlists and photo albums in iTunes and iPhoto. Then plug in an iPhone, click on it's icon in iTunes, and change the settings for Music, Photos, etc to only sync the playlists that you want on that device. Repeat for each one. They'll all remember their own settings, and continue to sync with their designated playlists or albums.
What you cannot do is use more than one computer with a single iPhone. That will wipe out the music and photos that were on it already, replacing them with the ones on the second computer.

Is there a way to order more than one type of card at the same time from iPhoto?

I would like to order a number of personalized cards from iPhoto, but I don't see a way of ordering them at the same time. It looks like they will all have to be separate orders. Is this the case or am I missing something? Otherwise, I pay more for shipping than I am for the card...in which case, I will just look elsewhere.
Thanks,
Denise

No - except for photo prints you can only order identical items as a single order - different designs or products must be different orders

No longer able to see more than one window on screen at the same time

In the last 2 days or so, I am no longer able to have a Safari window on screen at the same time as my Mail window. Same with Applications, I was working on a project in InDesign and wanted to check out how to print it booklet & double sided with my Epson printer but as soon as the Safari window is on screen the Indesign one disappears, which is no use at all for following instructions. I used to be able to have numerous windows available on screen at the same time (4 isn't unusual for me).
Does anyone know what has changed? The only thing I'm conscious of doing was moving my dock and hiding it so I've put it back to where it was and always visible but I still can't have 2 different windows on screen at the same time. Any help/advice gratefully received, thanks

Not sure I understand!
Do you get an error when attempting to have two windows opened?
A silly question on my part maybe but have you tried resizing the windows to more than one will be visible?
To re-size a window left click the mouse to grab the bottom right corner of the window, hold the click and drag the window up, down, left or right to re-size.
Alternately you can try clicking the green plus button on the on the top left corner of the window. This will automatically re-size the window to its best viewing size.
Did you by change change the resolution of your monitor from System preferences?

How do I keep more than one safari page open at the same time?

New to Mac. I'm used to being able to have several applications open at the same time, and able to check emails, eBay, camera for downloading photos, etc., but when trying this on Mac, I can't seem to figure out how to swing from email to something else....oh, it opens up eBay and other pages, but not where I left it...I have to keep starting from the beginning...name, password, etc. I can't have 3, 4 or 5 safari pages open at the same time?? This is making my life cumbersome, and running back to the basement office and using my dying Dell desktop where life was a bit simpler. Sometimes I need to copy a few paragraphs on one website into another....and its taking me way too long to get this done. I know there's a way of doing this on Mac....

Hi Suzkas,
I was new to mac a short time ago and I had frustrations in the learning curve especially as I was so used to working with PC.
If you look at the top left of the screen you will see the words SAFARI next to the apple logo. if not then either open safari or click on the window and the mac will then show safari at the top. If you now click on FILE you can select NEW WINDOW or NEW TAB as you wish. I often use new tab and switch between them. If you go to VIEW and select CUSTOMISE TOOLBAR you can drag an icon to the top of the safari window and you won't have to keep going to the menu to add a new tab. I will sometimes select new window to keep something separate from my other work.
If you close down a window you will often lose your place, but using the tab system you will leave the window active unless you select the cross to terminate. If you have a separate window open you can select the orange blob (between the red and green at the top) and the window will slide down to the dock and stay there, active, for you to return and continue.
Hope this help, stay with it, go see the instore staff and pretty soon you wont look back
PS I have PARALLELLS6 running with a copy of windows 7 on my mac. This means that I can switch to microsoft if I want to. However, with office for mac installed I rarely need to now, the only time I ever open windows is for an application that has no mac version.

Adding more than one controller to WCS at the same time

We are about to start a 585 location deployment with a Wireless LAN Controller (WLC) at each facility. Currently, I can only see a way to add controllers to the Wireless Control System (WCS) one at a time through the GUI. Does anyone know a proven method of adding multiple WLC's to WCS at the same time?

Presently WCS does not have any feature through which mulitple controllers can be added to the WCS. Controllers can be added one at a time only.
