Aliasing @ low speeds?

I received the mdo100 kit via Elektor, and built it, all seemed well, and I did the trimming, BUT...
1) reedrelais 1 is kaputt: when switching from DC to AC the relais sticks, and I have to tick it to release it... I will replace it with a new one.
2) when I apply a 1000Hz square wave, it shows OK in fast regions (200uS) but when switching to 100mS I suddenly see a square wave of 3-4 Hz, in stead of a "full screen"! That cannot be right, I think.
3) can the firmware of the mdo 100 easily be modified (as in the logic analyzer)?
Can anyone help? Thanks for your cooperation. Sorry my German is not good enough...
