You guys are not going to believe this but I went to take a screen shot of all my blank dialog windows and----------they're all up and working now!!!!!!!! And I can print any email in Outlook! I have NO idea what I did (or we did) that fixed these. Something I did today or late last night, I guess. Now I'm afraid to turn the computer off! LOL
The only things I've done since yesterday afternoon are check the regsvr32 things sawduster suggested, plus some more I found on Ramesh's site (they were all okay), and I moved all the deleted Norton files from the recycle bin back into the Norton folders to try again to uninstall them all, but hadn't done that yet (don't think I'll mess with it anymore now). Don't know why, but I thought moving them all back, and then trying the Revo again might get them all this time.
Anybody have a clue?!?!?
Thanks to everyone for hanging in here with me, but looks whatever was wrong is fixed. Big question, though, is it now safe to SP update, or should I just leave well enough alone with all the troubles I've had?

(Sorry, I'm getting a little carried away here!)
Hi Pam...
YAYYYYYYYYYYY!

No need to be sorry, I'd be ecstatic too!
While I'd be inclined to say leave it like it is, without upgrading to SP3, I'm not sure if you have or if you will continue to get updates to the OS, plus the increased security risk.

Also, OEM copies are designed for system manufacturers who agree to preinstall and support those versions of the operating system, rather than Microsoft, in exchange for a cheaper rate per copy. Legally, OEM copies are "wedded" to the system (motherboard specifically) they were originally put along with the COA and if the motherboard dies, then so does the copy of XP. There are more limitations. This particular post on CNET offers more detail...

The following information was found at Tek-Tips
ALL OEM copies can only be installed clean: (that is, the hard drive must be formatted before XP OEM can be installed). They cannot be used to perform an upgrade of an existing Operating System so make sure
you back up all necessary data and files BEFORE installing XP OEM, since the format of the Hard Drive will erase ALL data on it.
There are two types of OEM CDs:
1) an OEM version created by a system manufacturer. These copies are usually "BIOS-locked", and can only be used on the exact machine they were created for.
2) a "FULL OEM", or "FULL OEM DSP". These may be installed on any IBM-compatible machine. These may or may not be provided with a factory-built machine, but are usually purchased separately for installation a home-built machine.
You will be making a trade-off in buying an OEM version. YOU will trade the ability to upgrade an existing installation of Windows (and save
your data and programs) and the legal right to install the copy on a new machine, (if you should change your old machine for a new one), for a
big savings in the initial cost of Windows XP.
NOTE: OEM versions must legally be sold along with a hardware item, but in many cases this hardware item may be a power-cord (usually a $1) or mouse (they might even give you the mouse to satisfy Microsoft's
licensing requirements)
Three other issues that need to be emphasized about an OEM license:
1. You will receive no support from Microsoft. You will be referred to the original OEM licensee.
2. You cannot upgrade the FULL OEM DSP version. When longhorn or whatever appears this will not be a qualifying license.
3. Currently you can transfer (no, not two copies) a non-OEm license to a new machine. You remove XP from the first machine and the license will transfer to the new machine. You call Microsoft and they will issue you a new activation code. You cannot do this with the OEM license. It is for one machine only, the original machine. You will not be issued an activation code for a new machine.
4. You can upgrade the RAM, hard disk and other devices. And use the phone option to re-activate. The question is whether the OEM installation is fundamentally the same after the upgrade"
The "licensee" in #1 is you, in this case. Folks with these copies have to take care of the support end of it all by themselves.

The retail version offers more rights including the ability to transfer the OS to any system, provided you uninstall it from the previous system. The retail version is also Microsoft supported.
Hope this helps and I'm glad your system is up and running correctly again!

May God Bless you and your family!
