Scrolling on a mac

Having a problem using a mouse to scroll down on a sheet in grid view using Safari browser on a mac. When I use the mouse to try to scroll up or down, it jumps me to a different screen. I have to click on the sheet and use the arrow keys to move around. This is very frustrating and causes me to avoid using Smartsheet, especially for items that will require collaboration with others who might be using macs to access a sheet.
