I am working on a large size Excel file with Macro enabled. The file is quiet heavy and takes time to load. When I use to work on the same before, the screen flickers. That was acceptable as I can keep on working on the same. Now after getting fresh updates I cannot work on it. The update has created more issue in Excel. The screen flashes a number of time and the file responds too slowly. It looks like the update was not at all compatible with my Office edition. After removing the same things went back to fine. The file works properly. It looks the update is buggy or there is some issue with that. Any thoughts.
