Mark,
This is untested but if you have a back-up of your wdisplay.ini file you might try replacing the one that is currently in your main WD directory with it…
I would close WD and all related additional .exe such as realtime client raw and then take the current .ini file and move it to a new location as a precaution and then copy the old .ini file into your main WD directory and then restart WD…
However with so many things now being kept in the Windows registry I am not sure how effective this would be. I would back up everything first to be safe…
Another thought would be to create a second WD install with the information from this FAQ Installing multiple instances of WD on your computer and install the backed up .ini file into that directory first and then install WD into that and start it and see if your settings are there…
And of course the safest thing to do would be to wait for Brian to come along and see what he had to offer
