A bit of a 'numpty' question, but as I'm new to Discoverer please forgive me...

Is there a limit to the number of times that one account can be logged onto (and using) Discoverer?

We have problems that seems to be caused by more than one user using the same logon account to use Discoverer Viewer. We have set up a training session for users, but the trainer is asking everyone to use the same logon account.

The problems are various (e.g. pages of javascript appearing, sessions taking ages to perform tasks whilst others can perform the identical task in next to no time etc) - the problems don't occur if different (i.e. individual) logons are used.

So is there a limit? (the obvious answer would appear to be 'yes', but I'm trying to work out if this is a performance issue that needs resolving or a 'feature' of Discoverer.)
