When you double-click a shortcut to an unavailable network location or to an empty or disabled CD-ROM or DVD-ROM drive, and you double-click it many times, Windows 2000 will perform more slowly.
This behavior occurs because the desktop heap becomes depleted.
When the desktop heap becomes depleted, you must log off, or restart, to recover the resources.
NOTE: In Windows XP, double-clicking an empty CD-ROM drive, or DVD-ROM drive, does NOT deplete the desktop heap.
NOTE: In Windows XP, double-clicking an unavailable device, or network location, generally prompts you to delete the shortcut.
