Is there a limit to the number of tabs that can be opened in a single window of IE9? I have noticed that once I have a certain number of tabs open in a single window, any more tabs I try to open beyond that point will simply open a blank page that never loads the website. The number of tabs at which this occurs seems to not be constant. Once this occurs in one window, I have no problem opening new IE windows or opening more tabs in other existing windows that don't have as many tabs. What really puzzles me is that if this is a resource limit, I'm not sure what the limitation might be, as I'm only using 6/18GB when it occurs. Any ideas? Has anyone else noticed this?
