I have a web application using apache and MySQL.

This application uses an OCX developped in VB in order to connect to an ACCESS database to launch a calculation.

There is no problem if there is only one user who launchs a calculation.

However, I have an 'access violation (msjet35.dll)' error when 2 ou 3 users launch a calculation at the same time...
This problem is on Windows 2000.

And I can reproduce this bug when I install the entire application on Windows XP...

Can someone have an idea ?

Thanks for yours answers.
