While the many USB adapters seem to be easier to handle, we have had some bad experiences. Their stability is not always up to the task for industrial applications. This might not be an issue when you only use them to control your RS-232 lab equipment for manual experiments, but in our case we have fully automated lab systems running, where LabVIEW controls sometimes up to 8 serial devices and those applications are supposed to run day and night, if possible for many days in a row without interruption. With many of those noname USB-RS232 adapters we noticed various kind of problems. It could range from intermittent communication errors (which could be handled by additional code in our software to retry communication on such errors) to complete failure of the RS-232 port after some time, which could only got back online by unplugging and replugging the USB adapter.
For our purpose this was completely unacceptable and we ended up using ENET-RS232 devices instead which are working fine for months in a row.

How do you select individual items from within a group?

Hi, All.
New poster. Forgive me if I miss any forum etiquette.
Currently using Indesing CS6 on Mac Osx 10.7.4
I'm a relatively recent convert to Indesign from Quark, and one thing I seem to have continual problems with is selecting individual items from within a group.
For example I will have a grouped item, such as price marker that is comprised of several individual items, some text boxes, some rectangles.
I find there is no way to select a rectangle that is currently placed behind a transparent text box without ungrouping the entire item - which isn't really an option.
The select options (slect next item below etc. just don't work)
For any Quark users out there, the equivalent command I'm looking for is the cmd+opt+shift click through, which just worked absolutely perfectly.
I have scoured the internet and forums looking for an answer for this, as I assumed it must be my own lack of knowledge, but I can't find an answer.
Any help much appreciated.
Thanks

Hi, winterm.
Thanks for the super quick repsonse. Unfortunately that hasn't seemed to have helped me.
That works fine as long as the grouped items are overlapping or apart, but not when items are entirely behind another item (ie, no part protruding from the group)
The problem is that if I double click to try and get through a text box to an item that is entirely behind it, then it just switches into text edit mode for the top text box.
If it helps, could you imagine a transparent text box that is 20x20 with red rectangle centred beneath it that is 10x10. If the 2 items are grouped I cant find any way to select through to the red rectangle without first ungrouping the two.
Am I going mad?

Hi and welcome to the forums!
GREAT FIRST POST!! Very clear and specific. You don't know how rare that is
Is the laptop in a docking bay?
Content "encryption" meaning Content protection is turned off, right?
Are you able to backup and sync with the Desktop software?
Do you have the correct folders on the card?
Blackberry, music, ringtones, pictures, videos, voice notes?
(blackberry has to be first).
Last one, how did you format the card?
Thanks

I've got twin 12 year old boys and want to set I tunes accounts for them both, I need to be able to administer any purchases as they will need to use my bank account. How can I do this?

What do you mean by administer?
When you set up the account you have to enter a birthday and it has to results in being 13 years old or older.
You can set a Restriction that hides the iTunes and App store and another one to prevent in-app purchases. See:

How do I block this msg from always popping up "iTunes requires Safari 4.0.3 or later to be installed to use the iTunes Store within iTunes.

If you still have your old card listed on your account then try selecting the 'none' option and remove it and then try entering the card's details from scratch. If that doesn't work then what is the full error message that you are getting, and the card is registered to the same name and address (including format and spacing) that you have on your iTunes account ?

Hello, Lynne.
Thank you for visiting Apple Support Communities.
Here is a helpful article that explains how iTunes purchases are billed.
iTunes Store: How iTunes Store purchases are billed
http://support.apple.com/kb/HT5582
When using iTunes to purchase content for the first time on a new device, it may require you to verify your payment information as a way to authenticate your device. If this not a new device attempting to access iTunes store and prompting you provide payment information, there could be an outstanding balance. This article will show you how to verify you purchase history and invoices.
iTunes Store & Mac App Store: Seeing your purchase history and order numbers
http://support.apple.com/kb/HT2727
Also, you can change the payment method as none as long as there isn't an outstanding balance on the account.

I need to set up Firefox on my IPad 2 to be able to use my MLS system. How do I do this?

1. Mozilla doesn't have a version of Firefox for iOS, which is used on the iPad.
2. Most MLS services aren't compatible with Firefox, they seem to use software that needs controls that are only available in Internet Explorer.

You can change the email address of one's appleID...
I'd recommend changing moms email to yours to get a good backup on the Mac
Then switch mom's back to hers
Then change your account to the same email you used.
I've done something similar when I needed to update my Apple account (one ID changing email addresses and phone)

Hey KEBENNETT,
It sounds like you've restored Windows on your PC and iTunes is no longer opening and running normally.
I'd recommend using the instructions found at step 4 and 5 in this article to repair or remove/reinstall your iTunes installation:

All the best,

Hannahdb1 what specific Adobe applications are you attempting to reinstall? Do you receive any specific error messages? Finally what version of Mac OS are you using?
