This was a good catch on your part and helpful to other PowerPac users!
Basically what happens when you set compatibility view ON for a particular url is the IE browser will behave like it is running morphed IE7 or IE5 content (Quirks mode). ToolBook/PowerPac content is fully standards compliant when you check the PowerPac menu item Enable IE HTML 5 Display. While browsers will automatically determine compliance from the content, if you tell IE to explicitly set a particular url or domain to use compatibility view, then all sorts of anomalies may occur because it will no longer read the compliance from the content. Anomalies may especially be evident in object placement and how button clicks are handled or even not handled.
The PowerPac has matured to a pretty high level at making ToolBook content work in HTML 5 standards compliance mode. Therefore, I really recommend checking Enable IE HTML 5 Display for all your projects. This gives you the widest range of supported features, even full CSS 3 support.
I hope other PowerPac users will benefit from this little forum conversation as well!
