MATLAB: Do I get a “device does not support” warning message when plotting data in MATLAB 7.0.4 (R14SP2)

"doesbitbltdeviceMATLABnotsupport

I have an axis on a GUI and I am plotting a few waveforms on it. The length of the data being plotted is increasing. To see the figure, run the attached BitBltTest.m file. To see the plot, press the "GO" button when the figure comes up. The program will infinitely add random points to the plot on the screen. After a while, when my screen saver comes on, the following warning messages begin to appear on the command prompt:
%%%BEGIN Warning%%%
Warning: Failed in BitBlt, device does not support this operation (gle00000006)
%%%END Warning%%%
I am running MATLAB 7.0.4 (R14SP2) on a machine with Windows XP Professional (SP1) OS and my screen saver is "Windows XP" (Windows default). This only happens when the screen saver password option is enabled. When I log back into the machine from the screen saver mode, I see the command window filled with the above message.

We are unsure why the "device does not support" warning message appears when plotting data in MATLAB 7.0.4 (R14SP2).
As a workaround, turn off the screen saver for this application.
