For some reason I can not resize Chrome's window to less than 595 px on Ubuntu 12.10. I can resize Firefox's window to 0 px. Also I can resize the Chrome window to a very small size on Windows. This is an important issue when it comes to web design and more specifically responsive webdesign where resizing the window to at least 320px plays an important role.
Does anyone know why this is happening and how to fix it?
