A family of Microsoft word processing software products for creating web, email, and print documents.
I found a solution!
After contacting Windows support, and not getting much help (They said it was an Office problem, then Office Support said I contact their commercial centre, as I was using a commercial version of Office, etc. etc.) I contacted Corel Support.
They were really helpful, asking for detailed report files from my system, and offering solutions to try.
In the end the trick that worked was to delete all of the temporary files on my system, and reset the Corel Designer workspace. This worked for Word and Outlook the as well the Corel program, so just deleting the temporary files should work for the two Office apps.
To do this, first restart your computer, and with no programs running, type %temp% in the windows search bar. This brings up one of your temporary files folders. Delete everything you can in this folder. You will not be able to delete everything, as Windows uses some of the files. Just choose the 'Skip' option for these files. You may need to enter some of the subfolders to get as much as you can. Then type %tmp% in the search bar. This brings up the second temporary files folder, and repeat the process. Then after a restart, see if the problem is fixed.
Alas, this had no desired effect on my systems. <sob>
Thank you for the effort though!
I have also found that this solution (for me) is only temporary. The problem soon returns, and you have to continually delete your temporary files to keep you cursors normal.
So I'm still waiting for a permanent solution, which I believe, would have to come from Microsoft, or the NVidia.
