I have not been using PicoScope for a year or so. In the mean while I got a new laptop with 64-bit Windows 7. But now I can hardly use PicoScope 6. From the Help, About PicoScope 6 menu:
PicoScope® 6 - PC Oscilloscope software version: 22.214.171.124
Copyright © 1995-2011, Pico Technology Ltd
Model: PicoScope 5204
Serial Number: QJY29/60
USB Version: 2.0
Calibration Date: donderdag 19 juli 2007
Hardware Version: 1
Driver Version: 126.96.36.199
The problem is that the scope traces do not start again after I change e.g. the vertical scale or change the trigger or start capturing after stop capturing. The user interface seems to continue to respond, but no traces appear.
When I remove the power of the scope, a window pops up ("check USB and power cables..."). After powering again, the scope reacts: the fan starts and some relays click, but no traces. I cannot close the program normally, I get a message "PicoScope not responding". After a restart, within a few clicks the traces disappear again. Looks like the software is waiting for the 5204 to respond.
Unfortunately, I cannot find a 100% reproducible erratic behavior...
