hello everyone. I am trying to use qucs (which in my mind seems to be the best of gui- driven, no hassle eda foss software) for a report i have. I hope you put up with my newbie questions

a) Transient simulations. Dunno why i just cant make them work... even a simple one like http://users.ntua.gr/el04092/bah.sch

b) I am also trying to make a dc analysis of the 741 opamp, but qucs doesn't like my voltage sweeping http://users.ntua.gr/el04092/1_2_apomonwths_dc.sch

more to come :)

any help highly appreciated
