ErrorMessage:EAccessViolation Event Code: AVAA0-0022-1

I've been having this error message frequently during the switching of different project's lay-outs from 1 lay-out to another which force eventually the P6 application to shutdown once I pressed ignore or abort.  Is this is something to worry about or just a mere requirement to have the P6 application to open again.

thanks,
