Something always interrupts my responses when chatting

Does anyone else have this problem? When I'm responding to a chat, in the middle of typing, something always interrupts my typing, and I have to physically click back into the chat box to keep typing. And it's gets annoying because sometimes, I have to click 5 or 6 times just to get one word typed. Also, I've noticed that when I go to pin someone's camera or select chat to chat with them personally, the cursor always gets deselected, and I have to click on pin or chat again and again just to select it.  I don't know if its because people coming in and out of the room, or what.  But is there a fix for this?
