Slow Printing After Loading VBA Print Event Handler

I have a MVBA print event handler that uses the IPrintEvents interface. I use it to collect print information. When testing Microstation CONNECT version 10.15.02.11 there is a significant delay in the print preview window and also the plot file creation. When I unload the MVBA all works as expected. Is this a bug? Here is the MVBA file:
