Open Dialog Box (not responding)

We have a XP Professional SP2 Running XP Office Professional Running SP3, It just started (1) day ago. When you go to open a doc from "file open", you get a freeze in the "Open Dialog Box (not responding)".  This is true for Word, Excel, Access and also from Outlook if you try to attach a file. On Thursday Afternoon we deleted Temp Internet file and installed about 850 fonts. Friday is when we started receiving this problem.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi LSwitzer,
Please see B-M-C's comment in http:/Q_21815502.html#16465442      Apparently, Microsoft rolled out a security update on Tuesday which conflicts with software installed with HP scanners, HP cameras and HP printers that include camera card readers. The cure is a registry tweak.

It's a conflict between a recent Windows Update and HP printer or scanner software.

See http://support.microsoft.com/?kbid=918165 for explanation and fix

Or do this (which is a quick way of doing what MS suggest):
Copy the following to the clipboard (it's all one line even if wrapped in your browser - paste into notepad and remove line breaks if necessary, and copy again)
Click Start, run
Paste into the dialogue box and hit return.

==Copy below here==
REG ADD "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Cached" /v "{A4DF5659-0801-4A60-9607-1C48695EFDA9} {000214E6-0000-0000-C000-000000000046} 0x401" /t REG_DWORD /d 1
