I've just changed to a two-row taskbar and now when I try to position the popup for this Gmail notifier it doesn't seem to work: I click the push-pin and move the popup so it is directly touching the taskbar. Then the push-pin pops out and the popup fades away. Then when the next popup occurs, there is a small gap between the popup and the taskbar. I can't get it to be exactly where I want.
Also, do we get email notification of new versions? I notice there is a multiple accounts beta version, but I nver would have known if I hadn't come here to write about this bug.
