I just don't get it

So, there's this lady at work who has been with the company for probably 15 years or so. She is a collector. She calls the client when they owe us money. She has two clients. All the other collectors have 7 or 8. I have to deal with all of them in some form. Well, one of the third party billing systems that some of our clients use (including 1 of hers) updated part of their reporting area last week where we can go in and fix any errors and attach documents before we actually submit the invoice. Only one office (of 30) of one of her clients is on this system. Today, she e-mailed me asking for the link to their site as she lost all the stuff that was on her computer. Apparently, she didn't have a working computer at all last week. So, this is the first time she is seeing this new version. Because of the changes, we consolidated how we were uploading the invoices. Before, each office had one "batch" for each of their clients. i.e. all the NC invoices for Chase were in one batch and we could only submit the batch as a whole. So, if we were waiting for documentation on one invoice, we had to hold up any other invoices in that batch. This new system allows us to submit partial batches. So we can fix what we want to fix, click submit and all the "good" invoices will go through and all the bad invoices to stay. So, because of this, the two of us trying to work just in one batch would be confusing. So, I'm just going to do it for her. And, apparently before, when she found any invoices with errors, she just e-mailed the office to manually enter it. When it would take like 2 seconds to fix and submit automatically. So, can I ask just what the hell she does? And I know she makes way more than me when I know I do way more hell work than she does. It's so aggravating. Seriously, she does nothing and is so technologically stupid it drives me nuts! The week she was without her computer, someone else was doing her work. And you know she got paid for that week. Ggggggrrrrrrrrrrrrrrrrrrrrr
