right click eats memory

After having both a Writer and Calc document loaded my Calc starts eating memory and taking longer and longer to show the menu when I right click. Cannot get rid of the problem until I reboot my computer. Does not happen when I use the upper Tool Bar for the same operation.
It’s a Dell Inspiron 5400 running Windows 10 10.0.19042 Build 19042

This is just an assumption - is the spell checker trying to find the correct options for the words that were under the cursor at the moment of clicking?

This is in calc and the majority of the time it is in empty cells.

It turned out to be an interaction with Nuance Dragon 15.30.200.17 and I am running Libreoffice 7.0.5.2.
Loaded the latest version of Openoffice and it also has the same problem.
Running Windows version 10.0.19042 Build 19042 on a Dell Inspiron 5400 AIO desktop.
