When I add a VST plugin to the wiring view, then close Gigperformer4 without saving first, the question 'Save changes to '. When I click ‘Yes’ or ‘No’ Gigperformer seems to close without problems. However, in the Windows Application Log (event viewer) an error and two informational messages are recorded: Error event id 1000 (Application Error) and 2 times event id 1001 (Windows Error Reporting).
This occurs for plugins from various vendors (but not all), including vendors that are known to deliver well-programmed plugins.
When I save the Gig before closing, everything is fine.
Gigperformer3 seems not exhibit this behaviour.
