I made a simple graphical object in Microsoft Excel 2007; I saved it as as web page and uploaded it to a document library. Thereafter, I used a page viewer web part to show my page. However, whenever I click on one of the hyperlinks the web page has, it opens inside the web part frame and not in another browser instance/tab. How could I achieve it?
This is more of an Excel issue than SharePoint. However, when you create links in Excel, there is no way to specify the target of a URL. (For instance, you would need _blank to create a new window). When you export from Excel, the target is set to _parent. Only way to achieve this would be to edit the HTML files themselves to replace _parent with _blank on the targets of the links.
