Please have a look at the attached screen shot. You will notice that the default placement (centering ) of gui for addition of drug (substance) is such that the menu items on left side are not visible and one has to use horizontal scroll every time. This can be dealt with by reducing the length of entry field by few cms.
Moreover, the "OK" button at the lower end of gui is out of focus (not visible and accessible by mouse) as gui is not resizing according to the display/desktop size.
This problem also occur with gtklp (printing gui).
I think, the gui is optimised for larger display, but fail to accomodate itself on smaller one.
Another issue with the substance entry (the same gui that is shown in display) is that though it allows previously added drugs to be selected for current medication, new drugs (which are not entered through menu, lists, substance ) can not be added from the same gui. This was possible in previous version and was more convenient way.
