I have a brand new Lenovo computer running Windows 8 When I record audio the waveform display lags behind the cursor. It makes it hard to see if the program is really recording. This doesn't happen all the time. It seems that the first couple of times I hit 'record' the display keeps up with the cursor. After a while it starts lagging. This happened on my old computer and is one of the reasons I bought a new computer. I'm still having this problem on the new computer. What causes this and what can I do to fix it?
