Crazy Screen Saver (Bubbles screen saver became super fast)

To reinitialize the Bubbles screen-saver, try this :

1. Launch regedit
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Screensavers\Bubbles
3. Open Bubbles
4. You will see two sub-keys : Screen 1 and Screen 2
5. If the key Bubbles and its sub-keys contain any data besides (Default), delete this data

If you wish to conserve the above data before deleting it, right-click the Bubbles key and choose Export.

I note that users were having this same problem since the early days of Windows, so it may be a very old bug that was never fixed by Microsoft.
