I have a V1.30 site that has been running great for years. All of a sudden, the drop-down menu in the Administration section has started displaying strangely. Say for example you moused over "Catalog", then on "Products". All of the sub-menu items under Products are shown over the other menu items rather than off the the side, and they obviously can't be clicked.
I've posted a screen-shot here: https://www.dropbox.com/s/opnt31xi9b14qq6/AdminMenu.png
Any suggestions on why this might have happened and more importantly, how to fix it, would be greatly appreciated.
The site is running on Windows 2012 R2
