If you try to update your Google Places (business listing) listing on Google Maps using Internet Explorer, you may run into an issue.
A Google Places Help thread has confirmed reports of an issue that prevents certain versions of Internet Explorer from updating their business listings in Google Places.
The first report came three days ago, and Joel from Google confirmed the bug saying:
Thanks for letting us know. This issue may be unique to Internet Explorer. We're currently looking into a fix now. You can consider it a known issue at this point. It may take us a bit to put a fix into the product. For now, the best work around mentioned is to use another browser (people have reported success with Chrome & Firefox).
I'm going to merge other threads with this one.
We already can reproduce the issue in Internet Explorer 7. If folks see it in other browsers, please let us know.
I personally tried it on Internet Explorer 8 and it worked fine for me. If that doesn't work, download Firefox or Chrome until Google fixes this issue.
