Please have the save button become "faint" after you have saved a calculation as in older versions and then "bold" after you changed your input alerting you to save again.
It is annoying to get the pop up window asking to overwrite your calculation all the time because you are not sure if you saved it already.
This is a great idea. Did StruCalc 7.0 an earlier version do this? I don't remember that far back! I have added this to features for StruCalc 10.0. Thanks for your input we love incorporating user ideas into the program.
