Flashing of Embbeded applications
In most cases, clicking on RR's skin with an embbeded application will cause the application to "flash". The application flashes because RR's window comes up in front of your embbeded application. The way to "fix" this is to clip out that area of RR's window so it does not come up in front of your embbeded application. Once the area is clipped out of RR's skin, that region of the window will not surface above your embbeded application, preventing it from flashing.
The clipping definition must be added in your Application's screen (.skin file). Basically you'll open the .skin file and look for the line that starts with AXX,xxx... copy and paste this line as a new line and change the "A" from the new line to a "C" making it look like CXX,xxx...
Once the clipping definition is in place, it is normal to see "through" the screen while the application loads (in the space where the application will embed). But once the application is loaded, it will not flash when clicking in RR's skin.
