I've just installed 5.21.5 on a 64-bit Windows 7 PC, and have been trying to use it with an ADC-20.
However, the response of the user interface is so slow to the point of being unusable. After a while it freezes completely.
For example, when trying to configure the input channels, it can take anywhere between 1 to 5s to respond to each mouse click on a button. I've not managed to get as far as logging anything yet.
I've tried uninstalling and re-installing, but no improvement seen.
Any suggestions please?
