Anything BT decides to install on their engineers’ laptops. Most stuff is buggy or bogs down the out-of-date laptops, they can’t even sort out simple things like making the cursor tab along boxes in the correct order, so you end up tabbing and then alt-tabbing back to the bits it decides to skip.
Anything that is really rubbish, they develop work-arounds that involve resetting various things and restarting the laptop, as those that created the offending software have moved on to another project.
My new laptop…to open a particular website via a link in a program, you have to open IE first, otherwise the program and IE grind to a crawl, then when you try and save the files contained on the website, you are unable to choose a location to save them. Plus I have to reset IE’s advanced settings twice a day as when I try and sign in to the corporate website, it opens three windows and an error. Apparently its a known issue with no fix…
