B+ slows dramatically with 2 monitors.

Blitz+ canvas operations slow in dual screen.

I’ve noticed that Blitz Plus canvas operations (Displaying text or graphics on a canvas) are very slow if you move the app window to a second monitor.

I have a favor to ask. If you have two monitors can you run my test app and see if the number at the bottom changes as you move the window between monitors.

I get a dramatic difference. The app is 100's of times slower if the window is in on the 2nd monitor.

Any ideas on if this is a Blitz+ problem or a graphics card problem?

I have a Matrox G550. Identical resolutions , both 16bit color, different refresh rates.

Thanks a lot for any help here!
