Tool windows are disappearing / editor pane maximizes on maven project changes

I have a multi-module maven project opened in IntelliJ and everytime I change one of the pom.xml files (so everytime a maven related change is triggered) all my tool windows disappear. I then use SHIFT+F12 to restore the layout but it is a real pain in the neck. Even if I update my verison controlled code base and a pom.xml was changed or a new pom.xml file (or the removal of a pom.xml file) is part of that update, the maven update starts and *pow* all my tool windows are gone.

Does anyone know about such an issue or a reason that might be a cause?
