Xojo Inc. just announced the release of Xojo 2016r4.
As the new release changes graphics on Windows to use DirectDraw instead of GDI/GDI+, the plugins need to adapt. The handling on graphics ports (HDC) and for bitmap access changes a bit.
We recommend to use MBS Plugins in version 16.5 or newer with Xojo 2016r4. You can download pr9 now or wait for the release next week.
