Hi Nataliya
Hope you found your Excel VBA course a great help.
It sounds like the refresh rate on you monitor has been changed. To alter this right click the windows desktop, then go to the settings tab and then advanced and then select the tab that says monitor and you should find the refresh rate settings.
Hope this helps
