When using the dock to show running programs... Often I will notice that one of my minimized programs on the dock has lost it's thumbnail representation and is now just a normal icon. Has anyone else experienced this? Is there something that can be done to minimize this issue (pun intended).
Update: Actually, I've determined that any minimized applications will lose their thumbnail and revert to a normal icon representation if I close any program. To recreate this, open two programs, minimize one and then close the other. The minimized program will lose its thumbnail representation.
