kmacos9: Sluggish Finder

Sluggishness - in OS 9.1 and OS 9.2.x, there is often an interference between the Apple CD/DVD Driver and the Iomega Driver extensions which causes that problem. The test for this - insert a zip disk in the drive; if the sluggishness disappears, you have this interference problem. Solutions -

1) If you never use the zip drive, disable the Iomega extension.

2) If you sometimes but rarely use it,

• just leave a zip disk in the drive, or
• 
  
• you can disable the Iomega Driver extension - you can then use Iomega Guest to temporarily load the driver when you need to use a Zip disk; when finished, use Guest to disable the driver once again. If you need the Iomega Guest file, you can obtain it as part of the Iomegaware update, here - IomegaWare

3) Usual long-term solution - downgrade the Apple CD/DVD Driver extension to a version earlier than 1.4.5, such as 1.4.4, 1.4.3, or 1.4. You can download those here - http://www.panix.com/~dac/macdgm/ - at the bottom of the page.

Another cause can contribute to this problem: if you've updated QuickTime in recent months, you probably now have version 5.0.5; that version adds a new file, which can slow down Finder's ability to refresh the display of certain files. Look in the QuickTime Extensions folder (it's a separate folder in the Extensions folder) - if you find a file there named QuickTime JPEG Update, try removing it and restarting.
