1- it seems ok to turn off the pc monitor without affecting the capture, definately with BG mode
2-Whilst in BG mode it seems that any other audio is also recorded, so best leave the speakers on, as some sites automatically start playing a video
3-from version 8.8, the control panel is auto resized, but the sound volume is also changed...if set at 75% it will change to 48%...Rename or delete wmcsln.exe in the install folder to inhibit the resizing
4- The two audio sound bars seem to do notihng, apparently do not work on some systems, should be a disable button for these, if they are indicators only

This is an excellent program and am very impressed
