Subject: TImageScrollBox.DisplayedGraphic.Canvas.Pen.Color change from 2.0.1 to 2.5

I just recently (finally) upgraded from Envision 2.0.1 to 2.5 and everything is working great. However, I've noticed something that has changed and wonder if its intentional or not, and whether there is a work around.

I'm using TImageScrollBox to load jpg images that are in ifGray256 image format. I am then using the TImageScrollBox.DisplayedGraphic.Canvas property to highlight (draw boxes around) certain areas in the image using the Canvas MoveTo and LineTo functions which use the Canvas.Pen Width, Style, and Color to draw. In 2.0.1 I can set the Pen.Color property to a non-gray color (red for example) and the line would be drawn in the desired color. It appears that in 2.5 (perhaps because the underlying image is ifGray256), that anything drawn on the canvas is converted to gray. Is there a work around for this?
