RC3 on W7 64 running dual-screen. This feels like a stupid problem, but I can't move the QCAD main window with the mouse. I've uninstalled and re-installed but the settings revert to the same. I can use alt-space to move and resize the window, but it makes it difficult to use. I can't grab the top bar with the mouse, and the maximize/minimize/close box is not displayed.
Sub-windows like the layer display are fine I can stll grab and close them with the mouse. I can't remember what the main window should look like but it feels like it has lost its surround. Help!
