I came back from my hard earned holiday to find one of my users has a bizarre problem. During my absence her PC had to be moved from one desk to another, and ever since then, certain things behave as if the up cursor key is stuck.
For example, when printing (from any application) you select a printer from the drop down list of available printers, but as soon as you pick one, the selection will scroll back up through the list to the top one.
If you click in to change the number of copies you want to print, the number just keeps rising.
It only seems to be affecting scrollable lists, or selection boxes with up/down scroll arrows in them.
I've tried multiple keyboards, warm and cold reboots, different user profiles, a key remapping utility to prevent the 'up' key from working - all to no avail.
The PC is a month old HP 6000 Pro running Windows 7. I've trolled through my usual techie sites (including EE) but have only found similar problems that were caused by faulty keyboards.
Any suggestions? This is driving the user up the wall (understandably) and I've kind of run out of ideas!
