I have just a few minutes ago installed CYCAS 3.9.04 public,.. and looking thru the tutorial, and trying to draw the first item, a triangle, I find I cannot get the functions to work ,.. i.e. the help bar shows the same words no matter- "select function:". I cannot get the "line" function or any others to work.
I am fairly computer capable, and many years ago used some early CAD programs,...autocad, etc,... so I do not think this is a case of "operator error". I have not modified any parameters, settings, or options within the program,... only opened it, and begun the tutorial. I have tried closing this software, and re-opening, also tried the "Project / New " with no change in result.
I then re-installed the software. Still no luck.
My PC- Dell D610 with 2 MB ram,...windows XP Pro SP2.
Anyone have a suggestion?
