memory leak?

Windows 10 Taskmanager shows an increase of memory used by SR2 after repeatedly switching back and forth between craft designer, flight scene and Vizzy editor (same craft, script and flight scene). After a couple dozen times memory use has increased from about 1100MB initially, to about 1800MB.
Also craft designer and Vizzy editor become increasingly laggy and switching back and forth takes increasingly more time. Exiting and restarting SR2 resolves the issue.
