As I'm typing, keyboard output suddenly becomes corrupted and(because?) Japanese IME mode has changed. Firefox involved, or not?

Please see "troubleshooting" below.

In case there is dirt or food crumbs trapped under the keys run a vacuum hose over the keys or use a can of compressed air.
If the above does not work AND you do NOT have AppleCare, take the keyboard apart & clean it.

If you have AppleCare, call them & let them deal with it or take your MBP to your local Apple Store or AASP.

When Password Protected - The File Becomes Corrupted and I Can Not Open It

I have password protected two files now in Excel 2007. After opening and then saving a few times, the file becomes corrupted and I cannot open. The following error message appears "Excel cannot open the file"XXXX.xlsx" because
the file format or file extenson is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.
The files that I created contains sensitive information and I really need to get to them.l

You can try to open these files with 'Open and Repair' .
1.Start Excel.
2.click the Microsoft Office Button, and then click Open.
3.In the Open dialog box, click to select the file that you want to open.
4.Click the down arrow on the Open button, and then click Open and Repair.
Also this issue could be caused by malware on the affected machine
Please see:http://blogs.technet.com/b/the_microsoft_excel_support_team_blog/archive/2013/09/07/quot-cannot-open-the-file-because-the-file-format-or-extension-is-invalid-quot-opening-office-files.aspx
Some one works out this issue with remove the xlsx entention,give it a try.
1. rename the file and remove the .xlsx or .xls extention etc e.g. if my file is called test.xlsx I remove the '.xlsx' - you will get a warning message saying this could make the document unstable - accept it
2. the document icon should now have turned white (the document won't look like an excel document anymore)
3. open a blank excel document by hitting start -> all programs -> Microsoft office -> excel (this may be different if your not on windows 7)
4. in your blank excel document hit file -> open
5. navigate to the document you renamed above and select it, now click open

All the script and icons on my iPhone4 have suddenly become enlarged and it´s almost impossible to use them

After making a call on my iPhone4 all the script and icons suddenly became enlarged and it´s now almost impossible to use the phone. Everything is slowed up and only partial amounts of the screen can be seen. Any idea´s on how to restore to normal?

Thank you. All in order now!

After using an ExtendScript (via ESTK) Illustrator becomes corrupted and "Can't open illustration."

Hey, thanks for reading.
I'm having a strange problem with Illustrator CS5 and ESTK CS5. I'm new to writing ExtendScripts, so I haven't a clue what could be going wrong here but here's the skinny:
I've written the following code, which is very specialized to the exact document I'm working with. Using the ExtendScript Toolkit, the script goes through the following loops:
The primary problem:
For some reason, running this script causes Illustrator to become somehow corrupted. I can continue working with the document as long as it is open, but if I try to close it and re-open it, I get the infuriatingly unhelpful error dialog "Can't open illustration." With no extra details.
The same error comes up if I try to open any other .ai files. Shutting down and rebooting doesn't fix the problem. I have to completely uninstall Illustrator, then re-install it before it will work again. And even then, if I try to open the ExtendScript-corrupted file the whole Illustrator app gets corrupted and needs to be reinstalled.
Oh, also Illustrator itself shows up as "(Not responding)" while the script is running, but the ESTK console clearly shows that the script is chugging along as expected.
Specifics about the script:
There are 4 "Buttons" on the document, and a library full of nearly-identical symbols in the Library (different colored backgrounds for the buttons).
The script cycles through every symbol in the library, replacing and deleting instances of the previous symbol.
Then, for each symbol, it cycles through an array (technically an object-literal) of { language-code: "string" } pairs, and saves a .png of each artboard for each word.
What follows is a pared-down version of the full script:
(I tried to add a few $.sleep(10); calls, hoping that maybe just a brief slowdown in the processes might help. It didn't.)
This script (in its original form) outputs a ton of files very, very quickly.
Script Example
var folder = Folder.selectDialog();                     // Ask for a folder choice.
var aDoc = app.activeDocument;                        // Declare an active Document reference.
var textLayer = aDoc.layers.getByName('text');   // Get the text layer, for moving it back/forward
var textFrms = aDoc.textFrames;                       // Get all text frames, for language swap
var allSymbols = aDoc.symbols;                         // Get array of all symbols in the symbol library

Are there best practices that I'm unaware of here that could be causing this corruption?
Does anyone know what could be happening?
The only error I ever get is "Can't open illustration." There's never anything more helpful, so I have no idea what could be going wrong.
If there's any more information that would be of use to anyone I'd be happy to share. This is wasting a lot of my time and making me pull my hair out like crazy,

I have not had the time to look over your script but at a glance there are a few things I would handle differently…
Firstly returning a document to a given state… If you play with this snippet you can see that app.undo() returns to the last called app.redraw() if there is one else it undo's the whole script…
#target illustrator
doSymbols();
function doSymbols() {
    var doc = app.activeDocument;
    var sym = doc.symbols[0];
    for ( var i = 0; i < 4; i++ ) {
        var foo = doc.symbolItems.add( sym );
        foo.position = Array( i * 72, -( i * 72 ) );
        app.redraw(); // Comment this out to see…
    app.undo(); // Returns to last redaw state if any…?
Secondly your symbols… You know you can just change the symbol instance's symbol reference…? If they are almost the same particualy size then its an easy swap…?
#target illustrator
doSymbols();
function doSymbols() {
    var doc = app.activeDocument;
    var sym = doc.symbols[1]; // Next symbol in the palette
    for ( var i = 0; i < 4; i++ ) {
        doc.symbolItems[i].symbol = sym;
        app.redraw();

My ipod has suddenly 'zoomed in' and it won't zoom out. the touch screen does not move properly, and i do not know how to zoom it out

My ipod has suddenly 'zoomed in' and it wont zoom out. the touch screen is not moving properly and I have looked in settings but there is no where to 'zoom it out'
does anyone know how to fix this?

It is three fingers, not two. From the Users Guide:

Why have my Logitech wireless keyboard and mouse suddenly become poky and erratic?

Hi, I'm running a new mac mini (Dec 2014) with 10.10.2 on it. Out of the blue today my Logitech wireless accessories (with unifying receiver) became very sluggish with overall slow response times and at times the mouse is completely unresponsive. It really was working just fine until today. I went out and bought a new mouse to see if that would rectify it - and I still have the same kind of odd mouse behavior.
What's different between today and yesterday? I installed Dropbox and the new Microsoft '16 suite. I can't imagine that those two suites would impact a keyboard and mouse. I even did a refresh of the O.S. Any suggestions?

Thank you for trying to assist me Bob. Here's my EtreCheck output.

Is it possible for the Keyboard assignments to become corrupted?

I have an odd problem in that one of my programs that uses the space bar to toggle views has become very erratic. It moves from its assigned function to doing another one. When I first open the program it works properly. As soon as I move to another App, using Application Switcher, then it reverts to another function and stays there until I close and restart the program. I have checked carefully and there is no conflicting key assignment that could be an interference. I have tried reinstalling the problem program with same results. I have also deleted program prefs without fixing it. (It is not a program you would know — used in the practice of homeopathic medicine.)
I do use Keyboard Maestro and have assigned some key commands with it, but nothing that would interfere that I can see. Seems to make no difference if I turn Keyboard Maestro off or not.
So..I am thinking there may be some corruption with the use of the keyboard in some way? Is there a prefs file I should try deleting? Have not run into this before and not sure how to proceed.

HT1551 Can apple please answer the persistent question on why Hulu services, personal video via airplay, Netflix, suddenly stops working, and yet all along it has been working well on Apple TV? This is in contrast to YouTube, which is working without a fl

Hulu, Netflix and my personal videos have been working fairly well on appletv. Suddenly, without warning, they have all failed. My subscription via my apple ID is on automatic renewal, so the issue of non-paid services does not arise. On the other hand, YouTube is working perfectly well on appleTV.
Several solutions offered in the discussion group such as setting the appletv on sleep mode are not technical solutions. Rather, these solutions offered remind me of analogue age, when one had to hit the side of a TV set when reception failed.
In my case, I am using the same HD TV set that has been working all along. A new cable has failed, but if I am told to pay for an advice related to a fault that is not mine, I would rather buy a set box that is void of appletv or apple.
Apple please give a clear, well defined technical solution on the problem with your device, and to be specific on the following error:
"This content requires HDCP for playback"
I know what HDCP is, and one cannot say that this is related to a dynamic code that evolves with time, failing at a time of its convinience.

It is considered rude to double post on a fourm.

Apple Id has become corrupt and I can't fix it

One of my Apple Ids is demanding a password and the one I have always used doesn't work any more. I suspect it has been hacked because when I try to fix it I can't get past the security questions as it won't recognise my birth date. Moreover, when I ask to reset the security via email, I never receive an email so it looks like the password, birth date and email address have all been changed.
When I say 'one of my Apple Ids' I mean this is an old one that I first set up when I got an iTunes account, before I got either my Mac or my iphone. The account ID is an email address and to make things easier I'll call it by its short name of Lyonnesse. When I finally went Apple I couldn't log on to the account and set up a new one in my proper name - Helen for short - using a gmail account
My iphone is syncing to icloud using Helen and any photos I take on the phone have been finding their way onto my Mac, and into iphoto, but iphoto is now showing I have an issue with my icloud account - it tells me to check my settings. Opening icloud in my system preferences shows me that Lyonnesse is the icloud account. It won't let me change this without the password. I tried to add Helen to the list by pressing the plus sign in the bottom left of the list but when I saved it, i got a message saying it was already logged in.
I genuinely don't know where to go next with this. I'd ideally like to lose lyonnesse and just use Helen, but if I try to sign out of lyonnesse it says "Are you sure you want to turn off iCloud Photos? Photos that have not been imported will be deleted from this computer". I have to say, I find this immensely confusing. From where I sit, if they've not been imported they can't be deleted
How can I get back control of the lyonnesse account? There doesn't seem to be any help available from Apple. The Mac is outside its guarantee period so I can't get a call with a human being
Sorry for the long message but I'm trying to give the right information

Since have completely lost control of that Apple ID and neither recovery email nor security questions are working any more, you need to give Apple Support a call - only they will be able to help you. See this webpage on how to contact Apple Support in your country: There are either telephone numbers given or an email form:
Apple ID: Contacting Apple for help with Apple ID account security
Explain, that you need help with an account security problem.
You can also try to email the iTunes Support using this form: https://ssl.apple.com/emea/support/itunes/contact.html

IPhoto 6 has become corrupt and I have lost 50 amended images

This is my second post re a major/ serious corruption issue I have with iPhoto 6
Within my library I have 50 images that have had multi amendments made and each amendment has been saved as an image revision (e.g. Image6 when 6 changes had been made)
I came to use some imges this week and found that the thumbnails in the relevant iPhoto6 folder show the correct 'amended' image - however on clicking the very original photo appears (e.g. image 1)
This is a serious issue as I sell these images as my business
I have back ups but im still confused how this has happened (I have not used revert to original at any time)
My apple specialist has tried a rebuild but the problem remains
Its not on all images
Any ideas? Anyone know a UK based iPhoto speciliast available for hire?
thank you

Note that you are posting in the iPhoto '08 forum and that answers for fixing library issues in iPhoto '08 may be different than doing the same fix in iPhoto 6 - it is safer to post in the correct forum - iPhoto 6 - http://discussions.apple.com/category.jspa?categoryID=143
Within my library I have 50 images that have had multi amendments made and each amendment has been saved as an image revision (e.g. Image6 when 6 changes had been made)
Since iPhoto does not have either a save or a save as capability it is important that you describe how you did the amendments and how you created the revised images - e. g. image1 to image6
In iPhoto all edits are applied to the image and the name remains - the only possibly way to accomplish what you say using iPhoto alone is to duplicate and rename the image prior to editing and then it is impossible for iPhoto to link the duplicated & renamed image back to the original image - as far as iPhoto is concerned both (or all 7 in your example) images are separate and have no relationship to each other

How do I fix the App Store app in mountain lion which has become corrupted and won't update!

I can no longer access the App Store so cannot update my system. Ant Ideas?

In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.appstore.plist. Move the .plist to your desktop.
Open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer ones.
If you want to make your user library permanently visible, run the below command in Applications/Terminal.
chflags nohidden ~/Library/
You will need to do that after any updates.

Every time I click on Firefox window &/or touch a key on the keyboard a NEW window opens and eventually opens up to some advertizement that I do NOT want to see

It happened to me again(which it ALWAYS does) when I entered the above question...and I got a add about something from APPLE and I do NOT have any APPLE equipment...

Hi asduane, <br /> Sorry you are having problems.
I guess you have picked up some sort of adware or malware. Try to check and get reviews on both software and download sites. Then take care to read the small print about what is being installed.
Run scans with multiple and up-to-date tools. Hopefully it will be easily detected and removed. I would not suggest you try any manual hacks or edits of the Windows registry. (Once rogue files are removed any residual registry entry will not normally do any harm.)
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
* [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner]
* [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]

* [http://www.bleepingcomputer.com/download/adwcleaner/ AdwCleaner: (for adware)]
* [http://www.kaspersky.com/security-scan Kaspersky Free security scan]
You need to use multiple and up-to-date tools as they will not all pick up the same things.
[http://windows.microsoft.com/MSE Microsoft Security Essentials] is a good FREE permanent antivirus for Windows 7/Vista/XP if you don't already have one.
Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.

As I'm typing, keyboard output suddenly becomes corrupted and(because?) Japanese IME mode has changed. Firefox involved, or not?
