Thanks for the most recent version of SMath Studio, I'm using it to teach my hydraulics class. I did notice, however, that you cannot longer enter Greek characters in text by using the "Cntl+G" keystrokes. The only way to get Greek characters in text is by clicking them off the "Symbols" palette. Could you restore the ability of entering Greek characters using "Cntl+G" in the next version? Thanks!

Thanks for your hard and valuable work
May I ask if the handheld version is being discontinued ?

Is "Ctrl+G" working for you both in Math and Text regions? It doesn't work in the text region for me as well, as Gilberto mentioned.
