A new release of gotMailG (v2.2) went out last night to address an issue w/ auto-login taking the user to the standard HTML version of Gmail instead of the regular version.
Included in that release was support for Google Apps accounts. Unfortunately, a bug in that code broke auto-login for anyone using "firstname.lastname@example.org" for their login. As a result, a new release (v2.3) is being released today. This release is just simple bug fix. Sorry for any inconvenience these multiple releases may cause you.
The newest version of gotMailG (v2.1, release today) corrects display issues associated with Mac OS X 10.5 Leopard. The new version should work on all Macs running OS X 10.4.0 or later.
gotMailG seems to have a lot of visual problems under OS X 10.5 Leopard. A new version that corrects them is forthcoming.
The gmail RSS feed is back online. Everything should work as it did before. If you applied my Cookie hack, you should revert to a clean copy of the widget.
So it is deffinietly a problem with Google that is preventing gotMailG from connecting. I have been in contact with Google and they are in the proccess of fixing it. Hopefully it will be fixed soon and we will be back in buisness. In the meantime, if you want a little hack that will make gotMailG work right now, let me know and I will post how to do it (it involves a bit of code editing on a per-user basis).
As of around 10:00 am PST on 3/27 GMails SSL-enabled RSS feed server seems to be down. It is giving a 503 service unavailable error. This will cause the widget to appear to hang with a '-' in it. This is normal. No RSS client seems to be able to connect, even google approved ones, suggesting that this is a problem on their end. The only acceptation is combination web browsers/RSS viewers like Safari which can use some cookie magic once you have logged into GMail on the web to view the RSS feed over HTTP instead of HTTPS. Hopefully, Google will fix this soon. If a solution can be found without their intervention, a new version of gotMailG will be released. Thanks for your patience.
