Hi Trevor,

thanks for your help! I'm using MediaLab v2008. The OS is Windows XP. Sorry for not having mentioned that.

What do you mean exactly by "permissions are set properly"? We have three labs. In all of them I installed MediaLab and entered the code. In two of the labs all computers are working fine - no matter which user is logging in. Only in one of them I have those problems. Do I have to set special permissions within MediaLab?

The third issue couldn't be solved be pasting the "Experiment Editor"-folder as suggested in the other thread. Neither did a new installation work out.

Regards,
Horst
