I'm connecting to a Windows 7 machine with desktop composition and all that turned on. It starts out in a non-composition mode where you can see portions of windows being drawn, but then it freezes for about 10 seconds, then resumes with desktop composition. At that point, everything is very smooth, and all the Aero effects are rendered. This mode is actually much smoother and much more responsive than the non-composition mode.
The problem is, in this mode, it seems that any time the remote desktop window changes sizes, such as through maximizing or restoring it, its stops drawing the display. The window goes completely black either for a minute or indefinitely. It seems to still respond to mouse events however, as the mouse cursor changes when I move it, and when the rendering finally resumes, it seems to have performed the mouse operations.
Any idea why this occurs or if there's a way to fix it? Is this typical, or might it be some software on the remote machine that could be causing it?

As a work around, you can press Ctrl+Alt+End to bring up the Windows security screen, then press Esc to go back to the desktop. This should help "re-draw" the screen.
For a possible solution, you can try disabling the Application Experience service on the remote computer to see if that helps.
