I am logged in to my PayPal account composing an invoice. Whenever I have to pause to get some information and then come back to the invoice, it is timed out. It seems to time me out after something like 5 minutes, and that is very short indeed. I have to log in repeatedly - perhaps 15 times - while writing just one invoice. Can the time be increased? I am sitting in front of my computer all the time, and I only pause to collect information.
