Updated to latest 6.4.1.
Mac OS X 10.11.4
When I use Barcodes or Charts in my reports, they will not render in VStudio Preview.
I can export them and preview them in HTML, but none of the barcodes or charts will render on screen when using the preview button. If I take the graphical items off, then it will render text just fine.
If I export the report to PDF - I can see all the graphical items when I open the pdf after export.
