My ipod will not connect to my home wifi, it can see it and asks for a password but will not connect. I have tried it at another location and it will connect to other wifi connections. I have another ipod that is connecting just fine to my home wifi.

- Reset the iPod. nothing is lost

The u, j, m and 7 keys on the keyboard are not functioning properly on my macbook air. Please Help!

The u, j, m and 7 keys on the keyboard are not functioning properly on my macbook air. In its place are a random assortment of keys (Ex - u = "eqrw" or "IOUY"). This randomly happened when logging back in after sleep mode. No liquid damage at all. Please help!

OK, I fixed the problem by doing a SMC (System Management Controller) reset as follows:
1. Powered off my MacBook and removed everything connected except for the power chord.
2. When powered off, I held "Shift" + "ctrl" + "Option" + "Power button" for 5 seconds or so until the little light on the front started to blink rapidly.
3. Powered up my Mac, which took a little longer than usual to start and tested the "missing" keys which now works perfectly again.
Just added another couple of years usage with my aging mac :-)

GPO is set for "Auto download and notify for install" but it does not work correctly on two of my servers.

Hello,
I have a problem with two of my servers. I have ~200 servers which are updating fine through WSUS. The settings are as you can see "3 - Auto download and notify for install" in the GPO.
This is the correct setting. I want to achieve that I can install the updates whenever I want on these servers. On client computers there is a strict schedule with auto installs.
My GPO works fine for 98% of my servers. On two servers (a big file server and a TMG server) the settings are made as you can see in the screenshots, but the updates still get installed automatically.
I have no idea what I'm doing wrong here... It is a big problem for me that updates get installed automatically on these servers.
Although the Policy and the Registry both say 3 the server behaves like option 4 is active.
I would be very thankful for any input on how to find out what's the issue here.

and was not able to find any sign of an admin installing it in the WindowsUpdate.log.
Then the Windows Update Agent DID NOT install this update, and it's not really a WSUS issue.
My typical response to such a claim would be to ask you to show me in the WindowsUpdate.log where the update was installed... but it seems that request has already been answered.
The more relevant question it seems, is HOW DID these updates allegedly get installed?

GR and GI for the Subcontracting PO are not aligned

Hello,
We face an issue were the posting dates of the
GR(101 mvt) and GI(543mvt) for the Subcontracting PO are not aligned (GR takes
the posting date as the next day and GI as the current date).
We did an initial analysis and found that it is
the user time zone that leads to the different posting date. The user who does
the GR has a time zone setting of UTC+8 maintained in her user profile.
Whenever the user does a GR for the Process Order after 18:00CET, system
proposes the posting date for GR asthe next day. But GI picks the current date.
As per subcontracting scenario, the GI(goods issue from subcontracting stock)
happens whenever we do the GR. We understand that time zone has an effect on GR
posting date but the question is why GI posting date is not affected? Is it a
standard SAP behaviour?
Procedure -
We create the Process order via COR1 transaction,
In the master recipe we have maintained the control key for the subcontracting
operation.
Purchase Requisition will be created from the
Process Order. This PR is converted to Subcontracting PO via ME21N. The
delivery and PGI is done
via ME2O transaction. We have a custom transaction
to do the GR similar to MIGO transaction.

Hi Manikumar,
Empty the Personal time zone for the specific user & test the same. As by default, system time is maintained in UTC time zone.
Thanks,
Nihar

HT4718 I have OS 10.6 Tiger and I use to have DAshBoard and now for some reason I can not find it to launch it. Can anyone help me??

For some reason I can not launch Dash board anymore. I have used Finder and it is not there. What can I co besides take computer into service?

1. It's possible you removed Dashboard from your Dock by mistake. In that case, you can find it in your Applications folder and drag it back to the Dock to create the alias. The entire Dock are aliases.
2. If you cannot find in your Applications folder you can try re-installing the Combo Update I linked to.
This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.

Is it possible to get a refund for a game that is not functioning anymore?

Hi,
I recently bought a few bonus packs for a game called Valor that is not functioning since this Monday. I tried to contact their support but the only response I received so far was a macro message that in short explains that their servers are offline and they work on the issue. Three days later their status update still gives no ETA when eventually the service will be restored and I'm getting afraid that while waiting for them to fix the issue I might loose my legal right of refund. How can I proceed in that case?
Regards,
Martin

There's no defined time frame for asking for a refund since the iTunes Store has no refund policy; the official statement is that all sales are final. Any request for a refund is on a case-by-case basis and granted as an exception to policy, not a guarantee. I'd suggest waiting a couple more days and see if the problems are corrected by the developer. If not, then go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report the issue to the iTunes Store. It's possible that they will make an exception for you and grant a refund.
Regards.

Must click then click and drag for JTable Drag and Drop

Hi All,
I've been using Java 1.4 to drag and drop data between two tables in our application. Basically I need to drag the data from individual rows of the source table and insert it into one of the cells in the new table. This works absolutely fine and has made a huge improvement to this portion of our app. I've included example source code below that does a similar thing by transferring data from one table and inserting it into another (it's quite big and also not as well done as the example in our real app but unfortunately I can't send the source for that).
The thing I've noticed though is that in order to start dragging data I need to click to select it and then press and hold the mouse button to start dragging, whereas under W**dows and just about every other OS you can just press and hold and start dragging straight away. If you try this with a JTable though it just changes the rows you have selected so the drag and drop works but feels a bit clunky and amateurish. I'd like to do something about this such that it works like Windows Explorer (or similar) where you can just press the mouse button and start dragging.
Any help would be greatly appreciated - and if anybody finds the code useful you're more than welcome to it. Note that the business end of this is CustomTransferHandler.java - this will show you how to insert data at a specific position in a JTable, it's a bit of a faff but not too bad once you've got it sussed.
Thanks,
Bart Read

Hi again,
Well I've tried using the MouseListener / MouseMotionListener approach but it doesn't quite seem to work, although it does get the events correctly. I think the reason is that it doesn't interact correctly with the Java DnD machinery which is something that V.V hinted at. It's something that I may need to look into if / when I have more time available.
I have to say though that I haven't had any problems with scrollbars - we're making fairly heavy use of large tables and if you drag over a table with a scroll bar and move to the top or bottom then it scrolls as you would expect and allows you to drop the data where you like. For this situation I've used pretty much the same approach as for the toy example above except that I've implemented separate source and destination TransferHandlers (the source table is read-only, and it really doesn't make sense to allow people to drag from the destination table so I've essentially split the functionality of the example handler down the middle).
I'm not actually particularly in favour of messing too much with the mechanics of DnD, more because of lack of time than anything else. Guess I'll just have to put up with this for the moment. Doesn't help that DnD is so poorly documented by Sun.
Thanks for all your help.

How do I locate my ID and password for my One-to-One (not the same as my Apple ID)?

I have not used my new One-to-One for some time, and apparently failed to record the ID and password. The Apple website asks me for my Apple ID to set up an appointment under One-to-One, which makes no sense because my Apple ID is not recognized by the One-to-One program. I need to change that to my Apple ID, but cannot do that unless I can get onto One-to-One. Any suggestions?

Bought and paid for CS4 Premium, Acrobat Pro not accepting serial #

My Acrobat Pro application, part of the CS4 Design Premium, will not accept the same serial I used for my other Adobe applications.
Any solutions beyond tossing two hours of my life in a phone call to Adobe India Customer Service? I have had one good experience using Adobe CS out of five, but really it takes hours to get someone who is helpful. Adobe needs to address this brutal customer in need situation.
Apple buys Adobe, everything is fixed.
Solutions? Beyond waiting for Jobs to mount a take over?

I should add, I did install the complete CS4 Design Premium package in mid November 09. Worked flawlessly, until yesterday that is.
After some hours on the phone with Adobe customer service in India, finally the serial question was solved for all applications BUT Acrobat Pro. The tech said the serial number issue was caused by unknown forces. Odd, Adobe has a special number for serials not being accepted. It is a 1-800 number, I used it. I believe it is an Adobe made issue to keep pirated software out of the loop.
The tech said he would call me back in thirty minutes to confirm all applications were in perfect working order. I played with the entire group and AP was the dog of the bunch.
The tech never called back to check on me. That was nearly 24 hours ago. I anticipated this would be the poor result from Adobe.
I suspect I will need to devote another hour or so in Adobe Hell India Zone for a fix. The customer service is something which turns me off all Adobe products. When I find replacements for the software I will jump at the chance.

Try and force your iPad into Recovery Mode
1. Disconnect the USB cable from the device, but leave the other end of the cable connected to your computer's USB port.
2. Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.
3.While pressing and holding the Home button, reconnect the USB cable to the device. The device should turn on.
4. Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears, release the Home button. iTunes should alert you that it has detected a device in recovery mode. Click OK, and then click Restore to restore the device.
Note: Data will be lost.

HT201209 I have downloaded and paid for an app that is not working. It has no sound.

I have paid for and downloaded a book app - for my grade 2 students to use. It downloaded fine, but has no sound. It is "Go away, Big Green Monster' by Ed Emberley - I have deleted and downloaded it several times - but it still has no sound? What do I do to fix this problem or get my money back?
My next question is that I have bought and put in an itunes card to use on my ipad - but when I buy an app the ipad is still using my credit card and is not redeeming my itunes gift card - what to I do so that my gift card is used rather than my credit card?

If you open the App Store and go to Updates (on the bottom) and then Purchased (near the top), you will see your app there and you can download it again.
