I have been using Gmail Checker 2.6.1 with an audible notification for many years. It works only after a dialogue box appears and I enter my Gmail ID and password. The dialogue appears by itself (I have not found a way to launch it) and has a box to check to Save Log-in Cookies. It worked at first on my new computer, but after a couple of weeks I had to refresh the computer because of some nagging problems (thanks to HTG for the solution) and since then the dialogue box has not appeared and, consequently, I do not have audible notifications. Any ideas? Thanks.
