Hello @ivetta, 

 That sounds like you have too many windows open or that you need to clear the cache on your computer. 

If you are using a Chrome browser you click on the three dots in the top right hand corner > click on more tools > click on browsing history and then remove your browsing history for the last 24 hours or the last seven days. You can also choose to remove all of your browsing history, but I rarely have had to do that to get my processor running more smoothly. 

Another alternative method is to go into your task manager on a Windows machine and remove some processes that might be running in the background, but if you are not sure what to remove then this is an alternate choice at best. 

Regards,

Brandon
