Fixed it finally: click on (or hover over, depending on you Winsows setup) the Configuration tab in the toold bar. This will bring up a small version of the screen just above the toolbar for you to clock on. DO NOT. Instead, right-clock on it and select the "full window" (or "expand") option.
For some reason, my configuration screen was stuck to either a tiny-cum-invisible size or had been shifted to outside the visible area of the screen.
