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:

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.
