Gears may cause loss of data or problems like you're seeing. Can you check to see if you have it installed? The easiest way to do so is to look on the header of the website for either Offline (no Gears) or a green arrow (Gears). You can also look under the Tools menu (in IE) or the Options (in Chrome) to see if Gears Settings is listed there or check Google's site for more instructions specific to your OS/browser.

If you have it, can you try disabling access for Remember The Milk? You may need to reload the RTM site after this to make the change.

Let me know what you find!

Hi I have the same problem and have checked that I do not even have Gears installed.

corcosw,
If you haven't done so already, would it be possible to submit a Logging In & Loading issue report via our support system?

Please select the issue that you're experiencing from the list on the left, and follow the steps shown. If your issue isn't listed, just click on "I'd like to report a new issue" on the left.

Your report should provide all the info that we need to investigate further, but we'll be in touch via email if we require any more details.

Thanks!
