Hi Laurent The wxWidgets driver is currently undergoing a redesign in preparation for the next release of plplot. In the new version we will endeavour to ensure that we have no memory issues. That particular leak seems to be associated with plplot's internal storage buffer. I will have a look at what is going on and make sure any issues are dealt with and will keep you informed.
