HP Twain conflict with Caere Scan manager

This may be a Caere question, but it seems to be a specific conflict with HP, and I have installed Caere's HP patch--but still, no go.  So, I thought I'd attack it from the end of the scanner, as well as from the software end.

Prior to today, I was successfully running Omniform 2.01 and Omnipage Pro 8.0.  I was using Scan Manager 3.0 (the default install with Omnipage Pro 8), and everything worked beautifully.

I was--and still am --using an HP Scanjet IIcx.  I run Win98 and so I had to upgrade to a new Adaptec SCSI card in order for my computer to communicate properly with the scanner.  Again, no problems--I've had this computer since Nov. 1999 --which is when I did the SCSI and HP software upgrades--and all Caere scanning has been perfect.  I also purchased and installed HP's new drivers (version 2.8)--which were also required for win98 communication.  Again, everything worked perfectly until today's install of Omniform 4.0

After installation of Omniform 4.0, Omniform 4.0 works, all 'regular' scanning works, but Omnipage Pro says it cannot successfully communicate with my scanning software.  I have installed and uninstalled everything--the scanning software (which was--and is--current--I just checked the HP website), Omniform 4, and Omnipage 8.  I have also tried running Omnipage with three different scan mangers:  the default 3.0 (which it USED to work with), the 4.1 (installed by Omniform 4.0), and the new download of Scan Manager 5.0.  All the same problem--Omnipage cannot find my scanner.

I also tried the FAQ of deselecting the auto setting, so that I can select the Twain setting when Omniform starts.  No change--but, if this is a clue--I do NOT get an option to select my scanner (which is properly listed, though--by the way)--I simply receive the same error message.  The only other clue I can offer;  if I run HP's scanner test independently--not when I get the error message from Omnipage--but instead straight from the HP program options, the scanner passes.  But if I try to run the same test--which is suggested by the software--when Omnipage pro will not work--the  HP test just 'sits there' and does nothing.  

Again, everything and all scanning works, other than Omnipage--which--to reiterate--worked earlier today.

I am a fairly advanced user, but I'm about at wit's end.

rogerb,
Here is something you might give a shot.
Remove the following files and re-install the HP Deskscan II  software with all TSR's off.
C:\Windows\twain.*, C:\Windows\twunk.*,
C:\windows\system\hpsc*.*, C:\windows\system\hpsj*.*, then rename the C:\Windows\Twain directory as well as the C:\Windows\Twain32 directory to change the path for the files they contain, then reboot the PC. You will most likely get an error on the reboot saying a file hpsjvxd could not be found...this is to be expected and it is not a problem as you will reinstall it. A few of these files might be in use by windows and won't let you delete them from windows so it may need to be done by rebooting to a dos prompt.
Keep me posted.
