Why does the mouse 'run' to the lower right side of desktop and freeze when a SmartBoard is plugged into the USB port. Running 10.8.5. Sometimes the pointer has a cloud under it but it always freezes.
I run SmartBoards connected to iMacs running 10.7 and 10.8 throughout my school. On one of these computers the mouse has recently started freezing the minute a SmartBoard is plugged in to the USB port. The mouse 'runs' to the bottom right side of the screen, a cloud often is under the pointer, and it is not longer interactive. You can move the mouse upward a bit with the cloud following some of the time but it does not work. Once the SmartBoard is unplugged the mouse works normally. This particular computer worked fine with the SmartBoard until recenlty. Any solutions or ideas?
1. Reset the Pram and SMC

If these don't relate to your computer a quick web search will get you details
2. Run the Disk Utilty to verify the disk and then repair permissions.

My computer and itunes app do not see my iphone when I plug it into either USB port on the computer. The cable works because I can hear the iphone start charging off the computer. But there is no indication of the device in itunes or on my hard drive device list. Any ideas?
Have no idea what you mean by "basic stuff". Try EVERYTHING in this support article:

My computer freezes when plugging into my usb port
I just got and ipod shuffle when i plug it into my usb port a few seconds later my computer freezes and i have to restart
Try a different USB port. I had that issue with my shuffle once and using another USB port resolved it. Here is a great iPod Shuffle Support page. Keep it handy for anytime there is an issue or question regarding your shuffle. It's very thorough. http://www.apple.com/support/ipodshuffle/
Good Luck,

I keep trying to remove this check, but it always come back on its own.
Thank you for the reply, but none of those suggestions apply/or work. This is only a single preference that's not being saved. There is not a user.js file, but a prefs.js file and there is not an entry for crash reports on/off in it. These seems like a bug in Firefox, as the checkbox for the "Submit crash report" toggles back on the instant the dialog is closed, then reopened. In other words, just this one option is not saved. Any other options are saved when changed.

Why does the Point Stick on Dell Laptops suck so bad?
I have a Dell Latitude E6540 and a couple 7440's where the mouse will float if I use the pointing stick. I will use it for moving the mouse around and it is constantly moving after I stop. Let's say I want to close a window by clicking on the X. If I use the point stick to move the mouse vertically up and to the right, I will get over the X and lift my finger up off the pointing stick and the cursor will keep moving. It is SOOOO annoying. I moved to this laptop from a ThinkPad T420 and the pointing stick on that was so much better than this one. I hate using the touchpad, but when I'm fed up with this issue that's what I'll have to resort to.Someone, anyone, please shed some light on this situation. I can't believe that as long as Dell has been making laptops that this has not been an issue before. I can't be the only one affected.
Hi guys,I am about to order a bunch of hardware for my new vSphere home lab, my 16GB Macbook Pro is not enough anymore.The problem is I haven't been building PCs for ages so I am concerned I might miss something (e.g. fan, cable, tools?) or some of the components could be incompatible.So I would really appreciate your advice/help on the following shopping list (the prices are in AUD)I will have 2 ESXi hosts with SSD drives for vFlash Read Cache and 4x 1TB drives in RAID10 as iSCSI storage. Each host will have 16GB of RAM for now, will expand to 32GB later.I was thinking about 8core Avaton, but it doesn't have VT-d and is not significantly cheaper than E3, at least here in Australia.Also I thought about using Avaton as white box for the storage, but again it will cost me pretty much the same I would pay for Synology DS415+.Advice on the...

i tried to restart and re download everything and it still is doing the same thing. this keeps happening alot and i have to end up taking the ipod to the apple store to have them erase everything on my ipod to restart it. is there anything i can do at home to fix it
Have you tried to put the device into DFU mode?
To put the device in DFU mode,
1. Connect the device to iTunes
2. Hold both the power button and the home button down simultaneously
3. After 10 seconds, release the power button but leave the home button pressed
4. iTunes should then recognize that the device has entered DFU mode and ask to restore.
I hope that helps.

Why does the flash player work on some website but not others??
I have the new flash player, and for the most part the player will work on some web sites. However I like to be on myspace and it says that I have to install the new version of the flash player. However I ALREADY have the new verison. There are other site that I go to as well and it tells me the same thing. what is going on and how can I fix it. I am at my wits ends right now and I dont know what to do. Can any one help me please
I had the same issue when I had created Flash Paper items. I had found the a solution on my opinion.
http://www.eolsoft.com/freeware/flash_movie_player/
you actually need a Flash Movie Player and not Flash Player. they are different. the only issue is that Adobe does not support this anymore.
so what I did is placed the EXE file of Flash Movie Player found on the link above on my server, made a note to my viewers that Flash Movie Player is required to view the documents.
I found this solutlion when my boss asked why he could not view any of the Flash Paper Documents -
Acrobat is not on the USB device - only Adobe Reader needed on the PC. How does this work? How can I fix this device if at all?
You need to ask the people who sold it to you. Doesn't sound like it has anything to do with Reader.
However, you should be wary of devices that automatically try to open files when plugged in. They can also infect your computers with all kinds of viruses or malware. -
Vista x64, Dell Laptop Lately I have been getting audio ads from Lysol etc which I can stop by deleting the process plug-in container Iknow how to delete this process but why does the audio ad run despite the application of two well known antivirus progs?
Oh, PLEASE IGNORE the line:
deleted everything under HKLM\SYSTEM\CurrentControlSet\Enum\Root\SYSTEM (folders 0000 to 0004)
That was left there inadvertedly. Can't seem to find the edit button here... -
The I cloud on mu IPAd keeps reverting to my old password so that I cannot get mail. Sometimes this happens on my iPhone as well. I type in the correct password in the iCloud account and mail account under settings but it always reverts back and preventsme from getting mail. Can only retrieve mail from i cloud on my competer. Thanks!!!
Why would you delete your iCloud account for a password change with your Yahoo account?
Regardless, if no problem re-creating your iCloud account on your iPad, contact Yahoo technical support. -
Why does Magic Mouse use much more battery power than the keyboard?
I have the Bluetooth versions of the keyboard and the Magic Mouse. I use the same rechargeable batteries in each. Yet the mouse has now come to the end of a THIRD set of AAs, while the keyboard still has 60% of its first set.
Why? They are both constantly in use, so why does the Mouse drain batteries so much faster than the keyboard? Viz: the mouse about once a week (two, max), while at this rate, it will be another month or more before the keyboard drains.Actually I don't! I consider myself a 'power user' in that I will always use the keyboard first, and I learn keyboard shortcuts for nearly everything I do regularly.
I would guess my use is 50:50 at worst? -
