I've had this ever since I started using keyclone, and just worked around it.

Sometimes I need to use ctrl-alt-del to bring up the task manager. Either to kill a process, or to force the updating of a WoW screen which is rendering badly and hogging CPU (this happens to one of my instances with distressing frequency on zoning in somewhere new, but that's a separate issue. hitting ctrl-alt-delete always fixes it).

After hitting ctrl-alt-del, Keyclone seems to think that the ctrl and alt modifiers are still held down. If I hit "space", all my toons will receive "alt-space", for instance.

To fix this, I need to bring up the keyclone window and tap "ctrl" and "alt" in isolation. For instance, I can go to the "do not pass" section to get a field to type in. If I type the key P with no modifiers, keyclone will register CTRL-ALT-P. Tapping the crtl and alt keys in isolation fixes this "stickiness".

Has anyone else seen anything like this?

I'm running a pretty bare Windows XP Pro x64 install.
