Thanks for the reply.
As I said in my post I had already used groups to speed up the display of the 24 channels on my 3 pico loggers but it is still a pain not to be able to select all 24 channels in the log view for cut and paste into excel in one go.
Any reason why you put a limit at 20 channels rather than a multiple of 8 channels (as you get 8 temp channels on your data logger you see). On my 1024x768 screen there is amply room for more temp channels to be displayed - and of course windows does scroll left and right for smaller screens. I do understand the graph display would become crowded with more channels but that does not really apply to the data display.
Do you have any plans to expand the software to cope with more channels as returned by multiple pico loggers ? After all it may sell more loggers for you.....
If so when will it be available - I would be willing to try out a beta copy if that helps and it surely does not represent too much work.
