When I login to Blogger, the interface doesn't display properly. Everything is shifted and some buttons appear to be missing.The reporting volume, mentioning this symptom, is low - but it's not random, or zero.
From what we can tell, this problem started shortly after the latest Microsoft Windows updates, a week ago. Microsoft Answers: Computer Display Messed up After Restart discusses this problem, and essentially suggests that you should download video drivers from the vendor of the video device in your computer - and to not depend upon Microsoft, to provide you updated third party drivers.
If you are unable to use the Blogger Interface because the display is unreadable, with components missing or mislocated, you're going to have to update the video drivers on your computer, using drivers obtained from the manufacturer - not from Microsoft. This is not a problem caused by Blogger.
If the browser involved in the problem is Internet Explorer, you also may need to check your Compatibility View setting.
