I have an ADC-42 which plugs into the parallel port. When I run the Picoscope software the computer slows to a crawl, so bad that it takes me a couple of minutes to move the mouse pointer to the top-right corner so I can close the software down. This happens on the two machines I have tried so far, a 1GHz P3 desktop and a 2 GHz P4 laptop.
Running all other software including some quite complex DTP packages these machines fly along.
Any idea what I am doing wrong? OS is MS Windows 2000 Professional with all service packs installed. The machines are off the network and no anti-virus program is running.
