Also switch off 'Hot keys' in Hydravision properties. If you are using ATI card driver (Catalyst), try to disable the 'ATI Taskbar icon application' (Display Properties\Settings\Advanced\Options) and kill the atiptaxx.exe process in the Task Manager. If you have the 'Logitech Internet Navigator' keyboard, make sure you are using the latest Windows driver for this keyboard. I've checked that pickfirst = 1 (same thing but 'noun/verb selection' is checked) Since they are all rather old threads I thought I would start a new one.

I've searched this and other forums but the solutions suggested there haven't worked. I just installed AutoCAD Architecture 2014 on my home computer and the delete key doesn't work.
