I run a program called GradeQuick under wine in Ubuntu 8.04. It works well but occasionally I mess up and minimize the window, I immediately lose access to the window as it seems to be invisible to application switcher or indeed the task-bar. Any suggestions how to get it back when I do this? At the moment I have to open system monitor and kill the process, then restart the program and mentally flog myself for minimizing it in the first place.
