--- Comment #4 from mackle mackle9@yahoo.com.au 2009-12-01 06:42:06 --- Note: If Protel is loaded and window manager is reloaded, to compiz or metacity, the very small window is removed. However protel cannot be minimized by clicking it on the taskbar when it is maximised. It can only be minimised by clicking the - on the titlebar. I have also noticed this with various apps in windows in certain situations. Hope it helps.
