I've used WP for many years and never had a problem I have been using WP office 2021 for a few years now and all of a suden it stopped working. I found out the problem was caused by another program. I started using Stardock's Windowblinds again and it was the culprit. I run Windows 10 Pro, on an HP with a six core AMD processor and 32GB of memory. As soon as I stopped using Windowblinds, the problem went away. I use other programs from Stardock and they have never caused a problem. It seems to be a quirk, WP X6 and X9 worked fine but the 2021 didn't like the Windowblinds. Just putting the information out for folks who may have had a similiar problem. If you have been running WP and you have a problem, any new program you have added should always be suspect.
