Hello, I keep getting errors pop up under operations. Can you tell me how to delete them to stop them popping up. Thank you so much. ELizabeth
The best solution is to resolve the error, then it won’t pop-up again.
Or you can just disable the pop-ups in Menu > Tools > Settings > General > Operations Window, and hope they weren’t important. 
Gary, thank you very much indeed for this. I have disabled the pops up and they have gone!! I am VERY happy and very grateful for your help. Thank you sooo much! ELizabeth
