Different programs, different keys "stuck", so hard to tell. The amount
the pressed key is repeated differs too, from double to hundreds.

As an apparently separate problem my mouse warps once in a while too,
and that's not totally fixed yet, neither with that locking patch. Throw in
that two of my USB ports stopped working after a rare power outage, I
didn't totally trust my hardware any more, hence my initial reluctance to
report these problems.

We could have independent problems with more or less the same symptoms,
at least Teresa's problem seems much worse than ours, and if you and Ingo
only experience a stuck delete key, it might be something else.

Greetings,

Indan
