Thomson One only works with Internet Explorer (IE). And it only works properly in versions IE8 and below.There are some problems for Penn users accessing materials in Thomson One using newer versions of the browser. Some functionality, including downloading analyst reports, may not work properly. Fortunately, there is a work around.
Downgrade to an older version of IE.
If you are using a more recent version of IE it is easy to switch to Compatibility View.
Use the Findit box at the top of the Library homepage to access Thomson. Type Thomson into the Findit Search box and then click the link to the database on the left of the screen. Authenticate with your Penn Key information. Once in the database, click on the Tools bar at the top of the screen. Scroll down to Compatibility View and click open.
Once you have clicked on the tab you will see where you can add sites to the Compatibility View.
Once you click Add you will see that Thomson One is now in Compatibility View.
Click on Close. A small message box will appear. Click OK.
