Problem running

hello all
when I run and change sample rate from 1 to 2 the graph is
locked and i couldnot change anythig,
what is my fault?
Thank you.

This just means your PC is not fast enough to sample at that speed and
update the window. Try keeping the sample rate low.

Thank you.

Also try using:

fft-rate 5 --averaging

to reduce the number of updates, which also helps.

Well that should be fast enough, could you give us the exact command you
used to start

Also what do you mean by “installing ubuntu 10.04 using windows
are you running linux in a VM?
