On every tab is a Webbrowser control. As the webbrowsers take more an more memory for every new tab and they do not free this memory on tab-close, I decided to make a Webbrowser.Dispose() in the tab close event handler. This helped me concerning the memory leak. all the used RAM is now free after closing. But this caused a new
