I am playing with Gretl 1.8.6cvs on Mac OS X 10.6.2. 1. Bug? Load a script: two Gretl windows are now open (Main + script) The View menu is not activated but I do have two gretl windows open. -- 2. Why Scalars? Run for example klein.inp. Then we have a Main window, a klein.inp window and a script output window. Now the View, Windows menu is active and shows three windows: Scalars, klein.inp and script output. Scalars? There is no scalars window open. When I click on Scalars an empty scalar window is opened. -- 3. Window switching Switching windows on Mac OS X is easy: Command+` or Command+Shift+` which is an activity distinct from switching application. As it stands now, I feel that the Window menu is a bit too buried in the View menu. A main menu entry Windows could be considered. Some keyboard shortcuts to switch windows could be quite useful but the problem is going to be to find shortcuts that will operate on all systems. Ctrl+1 etc seems logical but won't work on Mac OS X Leopard and Snow Leopard because of Spaces. Of course, Alt+Tab is always available but that switches between all open windows. Ctrl+` to switch between Gretl windows only? Berend
