Inaccurate logging of accuracy

[Michiel Spape]

Sorry for barging in...
Just one thing I recently found out: the allowable and correct response can be set for each response device different. If you are like me and have both keyboard AND mouse as response-devices, make sure you have the correct response set for each one separately.

Don't know if something like this is happening - probably not, so ignore me - but it drove me insane the other day (it's very easy to overlook) and I hope to spare the rest such.
Best,
Mich

"What is the true response slide??"

A bad name for trying to name the slide where the actual response is
made.

"...so I'd tend to think that there then is something
      wrong with he correct responses you specified there."

Probably. I respond by left mouse button, and the 'correctresp' in a
list is set to 1. Also, the Allowable response is set to 1. So i don't
know what's wrong there
