The Folder Option applet does NOT have "extension" to select. It has 3
tabs: General (with Tasks, Browse, and Click sections) and a View and Search
tab.

Milly, is your suggestion for a Vista machine (like I'm on) or XP?

Thanks!!

After furious head scratching, Tom asked:

| Is there a way to enable the checkbox?
