Why does screen shift sideways without warning?

Since getting a new iMac with Lion, I have noticed that frequently the screen will shift sideways without warning, when the mouse has moved only slightly, and disappear. Sometimes there is an arrow in the lower righthand corner that allows retrieval of the lost screen, but not always. This causes particular problems when my son is doing schoolwork online -- sometimes the answers he had put down to questions will be gone when we retrieve the screen, or answers to matching-type questions will be scrambled. Is there a way to stop the screen shifting sideways?

It may also be inadvertently switching to another Space. See:
http://docs.info.apple.com/article.html?path=Mac/10.7/en/mh14112.html
and
http://www.maclife.com/article/howtos/how_use_spaces_mac_os_x_lion%C2%A0
If it's just switching to Dashboard, go to the Mission Control system preference and uncheck the box that says "Show Dashboard as a separate space".
Hope this helps.

Why does Firefox trigger the UAC warning each time I open it?

I design websites and test them across most browsers. We use Windows 7 operating system, and only Firefox triggers the User Account Control message on our test computers, which is a major annoyance when opening instances of Firefox in rapidfire order as web designers do. Is there a way to disable it? The UAC is not triggered by Opera, Safari, Chrome and we have made sure we have not checked properties-compatibility tab - "Run this program as administrator" in both the Firefox.exe file as well as any desktop shortcuts - as advised by several people and contributors to Firefox forums. But that doesn't have an effect. Each time we test, we get the Windows 7 UAC message. We've written to Microsoft several times and they have not replied. We thought perhaps you'd have a solution that actually works.
Thanks

I reinstalled first without deleting everything and then as you suggested. The program now comes up ok when I log in as administrator. However, it is the only program I have that suddenly won't work as a non-administrator without requesting that the administrator approve it to make changes to my computer. I have looked at the permissions and they are the same as for WordPerfect, for example. I don't expect that this program makes changes to my computer that will bother any other users.
Why does Windows 7 think that Firefox is going to change the computer for other users?

Why does screen freezes when I attempt to play certain songs in my library

Why does my screen Freeze when I attempt to play certain songs I have downloaded from CDs into my library?
I have just received my Nano and I'm unsure if I want this to keep happening

Apple removed my previous post because I referenced jailbreaking which is a violation of the TOS. Sorry about that!
That said, I can't think of any way to get around the file size limitation. I suppose itunes match isn't really meant to give you access to play all your songs anywhere. It instead gives you the opportunity to download your songs via wifi when you aren't at home. I can't see that it makes any difference one way or the other to Apple but it obvioiusly would make a difference to the wireless provider.
So now, my question is whether this happens on with all carriers. I have experienced this on AT&T. Does anyone here have Verizon or Sprint?

Why does Screen Resolution NOT offer orientation option?

This HP OMEN gaming laptop is the first PC I've owned (out of maybe a dozen) that doesn't offer orientation options on the Screen Resolution screen. Even the "help" thinks it should be there. I've searched for hours by now, wanting to avoid having to ask what should be so simple. For a seperate issue, I updated my graphics driver approximately 7/05/15. That issue was successfully resolved, so I know the update "took". Can't find it in any of the Nvidia choices either. SO many programs presume it to be available, many have stopped offering it within the program settings. Ideas, please? Thank you.

I took out the modules in mkinitcpio.conf, took off all the kernel additions, and borrowed a monitor from a different computer in the house. Everything says this should work, so i figured the TV may be the problem. It is. I had the TV hooked up with my Nvidia card on the old machine, and it worked perfectly. It did add fan noise, so I wanted to be rid of it if possible.
With the new monitor, it works perfectly. lsmod shows the i915 module loaded. Hook it back up to the TV (which is DVI to HDMI), nothing. This is some other issue, I think, so I'm marking this one solved.
Note: The SVIDEO line was wrong; a re-read of the archwiki page on KMS showed me that the line needs to be formatted as follows:
The format is: video=<conn>:<xres>x<yres>[M][R][-<bpp>][@<refresh>]"["i"]"[m][eDd]
so the line should have been video=DVD-D:etc, rather than video=SVIDEO:etc
Quotation marks above aren't really there; I can't figure out how to get a square bracket i to work without them; the forum kicks me an error.

RANT: Why does screen keep dimming even when "DIM" is disabled?

ARGH this is buggin' me!
I turned off the dim under custom in energy saver. i am reading a document and it keeps dimming and it's annoying as doo doo. anything i can do?

What about the option of "Automatically adjust
brightness as ambient light changes" in
Preferences/Displays?
William
William - anyone with this problem I can guarantee
shut off every screen dimming option.
I have this issue. It seems to be intermittent.
What seems to improve it - Restarting, or unplugging
and re-plugging in the mag safe charger.
These have been my only solution. I have even turned
off all display changes for battery power so that
there shouldn't be any "confusing" factors for the
computer.
I wouldn't care so much about this issue if it wasn't
for the screen whine with decreased brightness.
I trust apple will fix this with software or firmware
updates.
I checked my 1.67 PB 15", it does what is being described. Software?

Why does Test-EcpConnectivity throws a warning regarding the internal URL property not being set, when in fact it is set?

Hello,
I have setup an Exchange 2013 CU6 environment which contains the following:
1 machine with client access role
3 machine with mailbox role
1 machine with both client access and mailbox server role.
When I run the Test-EcpConnectivity against the machine which has both roles I get the following:
WARNING: The test couldn't test the internal URL of this virtual directory, because the InternalURL property isn't set.
But when I run "Get-EcpVirtualDirectory|fl" against the same machine, it shows that internal url property is set.
Why is this happening and how can it be solved?

Hi,
The Test-OwaConnectivity cmdlet has been deprecated. It is recommended to use the
Get-ServerHealth cmdlet to monitor server state.
Regarding the parameter of Get-ServerHealth

Why does screen saver prompt for secure disk image password?

Okay, seems like an odd problem, but here it goes.
I go into System Preferences->Dektop & Screen Saver. As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image.
Yes, I have a secure disk image in my home directory.
Yes, the secure disk image is currently "locked" (Not mounted in finder).
I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine.
I select a photo source that I want for a screen save and exit peferences.
I then go an start the screen saver (I'm using Hot-Corners).
I get the message "Looking for pictures....." for , well...basically forever...
Sure enough I touch the mouse to leave my screen saver and there is the pop-up again. Asking for me to unlock my secure
disk image.
I thought this might be related to Spotlight. I tried reading several threads and have gone as far as taking my entire hard-drive/volume
and putting it into the "Privacy" tab under spotlight.
Anybody have any idea on what is going on and how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my
secure disk image? (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity)
As always, I am only speculating that this is Spotlight related so that could be a red-herring....
thanks in advance.
OSX:10.7.3
imac/3.1G/Intel

Update: i made some progress on this issue. I found that in the ~/picture/iPhot Library/Database/ directory
there is a file called Library.apdb. This file has an entry for the secure disk image i have/had. I moved the file
to Libraryapdb.bkup and sure enough, my picture problem went away. The screen aaver panel no longer prompts
me to unlock my secure disk image.
So now the next chapter of my problem;when i open up iPhoto it wants to rebuild my photo library(which makes
sense and is what i want to haopen) so i allow it. After about 25 mins it has rebuilt the iPhoto library, but there is
one problem. The secure diskimage reference is back in the Library.apdb file that has been recreated!
So now i need to figure outnhow to get iPhoto to remove anynreference to a phot library i once had on the secure
disk image but have long since removed.
I first created an iPhoto library on my secure disk image by holding the option key and invoking iPhoto.
I removed that library awhile ago....
So how do i make iPhoto remove a no longer used iPhoto library?

When I open Reader why does screen flash and parts of document are not readable?

When I open a PDF my screen flashes, changes color and then when the document comes up parts of it are blacked out. When I close the document the screen flashes again. I have just downloaded the latest version of Reader.

The slowness may be caused by background processing after the library update. Are you shooting RAW?
Also, where is your iPhoto library stored? In your Pictures folder or on an external drive?
How much free storage do you have on your system drive
3. Finally when my old folders, books and contents of my old photo gallery appears in the left side of the application I have access to no photo and the program remains as it were unresponsive.
You may need to repair your iPhoto Library.
Run the iPhoto library first aid tools and use the options "Repair permissions" and "Repair database".
To launch the "First Aid Tools" hold down the options-command keys while double clicking your iPhoto Library.
Then select "Repair Database". Repeat with "Repair Permissions". If this does not help, back up your iPhoto Library and use the option "rebuild".

Why does MAS give me a warning when trying to purchase iPhoto '11?

I want to upgrade from 8.1.2 to 9.5.1, but when I try to purchase, I get this warning:
"iPhoto 8.1.2 is already installed and was not purchased from the Mac App Store."
Does the new download replace the current version or will I have to delete the older version manually?
If the new download replaces the older version, will my photos automatically transfer to the new one?
Is it possible to ask anymore questions in a single post?

The version you have installed came from a DVD installer, not from the App Store. App Store iPhoto cannot update the DVD version. You need to remove/uninstall the one you have, purchase the new version and install it. Removing or installing iPhoto will not affect your iPhoto library. But your should backup anyways.
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning

Why does screen freeze and jump?

I'm using 10.8.2 and the response is very slow and sometimes the open screen jump - what can I do?

I got your reply via email, however, it hasn't shown up here yet (?) You said "I have 3.74 GB outs and 2.31 GB ins - I have no idea what this means!"
When OS X runs out of physical memory to run programs, it writes sections of memory to the hard drive to make room for other programs to run. This making room is called a page out. In a memory perfect world, page outs would be zero, since there would be enough memory to run everything. However, that's rarely the case.
What your numbers mean is that, since your last boot (the numbers reset when you boot), your system has read in 2.31GB's of data to work on, however, it's paged out 3.74GB's or 162% of page in's. Where the gauge for the right amount of data is page outs being 10% to 15% of page ins, yours is at 162%, for the programs you run!
While you have 4GB of memory, your page outs suggest you need to at least 8GB for the programs you run. You could just replace one memory card to get to 6GB, however, the Intel architecture runs a bit quicker (3% to 5%) with matched memory, for example two 4GB cards.
That could explain why you've seen less than optimal performance, even with 4GB of memory.

Why does Screen Sharing between Macs no longer work?

Just recently many of my Mac computers have stopped Screen Sharing with each other. I cannot think of any reason why this would begin happening. These computers are 'system critical' computers so I haven't updated to Mavericks yet. One is an iMac running OS X 10.8 and the other is a Mac Mini running 10.7. Any clues?

This could be something as simple as a bad Router Port. Try switching the Ethernet cable on one of the effected Macs to a port that you know is working. When I was running computer labs, bad ports were a commmon issue. If that doen't work we will move on to other possible solutions.

Why does screen go white and unresponsive?

iPod touch screen goes white and unresponsive whilst playing games. Done it twice now and have to leave for a few hours until it clears?

You will probably never find out "why"
- To prevent try the following:
-- A reset. Nothing will be lost.
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
-- Restore to from backup
-- Restore to factory defaults/new iPod
If still a problem then you likely have a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Why does ctrl+shift+t many times open a random tab instead of the latest closed tab?

That's it, sometimes (I can't precise what causes it) when I dpressctrl+shift+t, firefox instead of undoing closed tabs, open a tab with a random website I visited some time ago. Like right now, I opened a tab with google and then closed, I then pressed ctrl+alt+t and it opened facebook, wich is a site I had opened like 10 pages ago

This can be a problem with the file [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete the files sessionstore.js and sessionstore.bak and any existing files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js to prevent Firefox from restoring a previous session.
