For no apparent reason my status bar height, status bar icon height, address bar height, and the address bar height on the download progress page have increased overnight for no apparent reason. Also, the status bar, while approximately twice its original height, now has a horizontal line bisecting it. I've tried changing fonts and pressing the - key while holding the Ctrl key. This changes the size of the material on the page but does not affect the address or status bar. I can't find anything that affects status bar height.
