I seem to be having an issue with my mac recently... Sometimes when I try to type, the mac beeps rudely at me and no text shows up. The only way I have found to solve this is to click off to another text field and then click back to the one I was on. I have found that this issue is only caused*when I use the mouse to navigate in a line of text or to another text box. When I use the arrow keys and tab to navigate text fields, no beeping occurs. Any idea what could be causing this? It is quite annoying to me!
