There's a problem (Windows) with the toolbars. With the huge code completion toolbar, I pushed the compiler toolbar far out of the visible area, on the right side.
Now I am no more able to see the compiler toolbar, the only way I guess is finding the entry in the configuration file. I even dragged the main window to the left, so only some pixels from the right side of the main window could be seen; then a resized the window to reach maximum right size. But the compiler toolbar can not be seen....
