When, for example we have a license instance that is applied to 10 machines, in the software license management, you specify the machines you need the license to be aligned to, however I have 200 machines and a scroll box with 10 visible lines. To select multiple items, I have to hold CTRL, and scroll up and tick the boxes. If I let go of control, and press a check box, I loose all the other selections.

This is especially annoying if I am trying to edit such an item, say a user leaves and the license is to aligned to another machine, and I accidently click the wrong box..... I no longer have any idea what machines WERE aligned to that license.

You use check boxes, not radio buttons, why do you need to hold CTRL to select multiple??????
