Please, please, please stop blocking pages from opening in new tabs. Certain links used to open just fine in new tabs in earlier versions of Windchill, but lately more and more of these will no longer work. Everything in Windchill should be able to be opened in a new tab with just the press of the middle mouse button.
Some examples of pages that refuse to open in a new tab:
Personal Cabinets Administration
Windchill Performance Advisor
Worker Agent Administration
Publish and Thumbnail Control
WVS Job Monitor
Middle clicking any of these links just opens them up in a new window. Right clicking any of them and attempting to load them in a new tab leads to this:
What's frustrating is that the URLs for each of these windows can be manually copied to a new tab and they all load just fine. This should happen automatically with a middle mouse button or a right click and 'open in new tab' command. Manual copying of URLs should not be required.
