You are running the new Tcl/Tk version of the Eurogam Analysis package. This has essentially the same functionality as the previous implementation with the following changes ...
Tcl/Tk has allowed us to remove the Sun system dependency from the package and so it is now essentially platform-independent. The package should run on any Unix workstation that supports the Tcl/Tk package together with X windows.
Tcl/Tk has a Motif-like Graphical User Interface (GUI). This is resonsible for the differences in appearance. Motif, like it or not, will be the primary supported GUI on Unix workstations in the future.
The LEFT-BUTTON is now the primary selection button, as opposed to the right-button in the old implementation.
The RIGHT-BUTTON now gives the default action (first in list) when pressed over a menubutton.
The Delete key binding has been altered away from the Motif default to delete the character to the left of the cursor.
Every menu has a dashed line at the top. This is the tearoff strip. A mouse hit on this area will transform the menu into a separate window.
There has been an enhancement to the spectrum access mechanism. The Spectrum Server is no longer necessary for access to disc-based spectra. The Spectrum Browser window has been changed to separate resource/server and file name. The spectrum server to be accessed (resource) may be changed by clicking the left mouse button on the "resource" label and choosing from the resultant menu. A blank resource ("direct" menu item) indicates direct disc access i.e. not via a spectrum server.
The spectrum display frame has been enhanced to include
... the arrow keys now perform left/right/up/down functions
... double-click on mouse button 2 causes a zoom at the click point.
... shift-double-click on mouse button 2 causes a zoom-out.
... click with button 1, followed by double-click causes expand
These functions apply to both 1d and 2d spectra.
Button 2 placed within 1 pixel of a tag (or on a polygon gate vertex) and dragged will move the tag (or vertex) to a new position.
Button 1 clicked over a polygon gate vertex will toggle the state between normal and activated (empty square).
The menus on the top row have keyboard accelerator features added. The underlined character is the associated key. ALT-key posts the menu.
The view menu has been altered slightly to include "zoom in" and "zoom out" functions which act centred on the last tag entered. If there are no tags defined, then the functions still work, with the left edge remaining fixed. The "expand" function now works for both 1d and 2d spectra.
A "reset" button, plus a row of 8 bitmaps now appears on the second row of buttons on the spectrum display window. The "reset" button acts the same as the vire menu reset. The bitmaps are mapped onto zoom-in, zoom-out, times2, divide2, left, right, up, down respectively. [The bitmap images are prototypes] The times2 and divide2 buttons for 2d are mapped onto contour level changes.
Display of 2d spectra now works on monochrome displays by using a bit density map. The full 16 "colours" only appear if the current spectrum expansion level causes a channel to be mapped onto a 4x4 or greater block of pixels.
