I am sorry to hear this is happening! I understand how frustrating this can be.
What browser are you working in? Do you have another browser on your computer that you can test in? If we can narrow this down to your specific browser it will give us a good idea of what to change.
If you don't have another browser to try please try launching your current browser in safe mode. Here's some directions. This will disable any add-ons you have running to rule this out as the problem. Once you have tested in safe mode, just close your window and reopen a new one to revert the browser back to normal.
