I bought an ADC-40 several years ago from Maplins. Tried it on a Dell laptop and encountered problems and recently tried it on an IBM. On both the speed was/is desperately slow with the mouse movements slowed to snail's pace. The scope does work. Then on trying to get a waveform optimised on screen, the software crashes. Windows Task Manager cannot be accessed and the only recourse is a power-off reset.
The symptoms are exacly as Loren noted earlier in January in a previous forum topic although the dignosis and suggested solution was much more complex. The symptoms are not intermitant: a crash every time is guaranteed. I tried both 5.16 and 5.18 but both fail.
The IBM is a Pentium 2GHz with 1.5GByte Ram and XP SP2.
