One of our users has the problem that whenever she minimizes a specific application, it gets minimized to the notification area instead of to the taskbar. The application does not appear in the notification area when it is non-minimized, it instead does appear on the taskbar. That is, unless she has focused on another application, in that case it does neither appear in the taskbar, nor in the notification area.
This problem is only present for this user, regardless of which computer on our network she uses, and does not appear for other people using those computers.
Apart from recreating her profile (which will almost certainly fix the problem) is there another way to get rid of this behaviour?
