New captioned image inserted into the Visual Editor produces a huge data-mce-style width (10000px+) moving the inserted image out of the editor viewable area.

The problem will be fixed in the next version V3.7.1, If you don’t want to wait for the auto-update, you can download the following  tinymce folder, unzip it and replace your old tinymce folder.

I have tested it and it worked.
