The ide freeze and becomes unresponsive. This happen on NB 6.8 M1. All my projects are maven based. After the freeze the ide is not recovering and must be killed. For the attached stacks and printscreen, the action that caused the lock was a double click (open) on a pom.xml But i reproduced this also on closing an log4j.xml and on a right click on a project an the "properties". I will continue to send updates (stacks/printscreens) as the issue is reproducing
