Windows 10 64bit Audacity 2.3.2
When I start Audacity I get a blank project window looking at a 16 second default…as soon as I hit record the entire track shifts to the right 8 seconds…I am able to record but Ive never seen a track move this way...when I stop the track moves back to normal Im trying to get a screen shot but am having trouble…when I hit print screen nothing happens…I may or not have captured the screen…but either way I can`t find it…can you help me with this ?
Thanks

Never mind I fixed it…I could use some help taking and saving screen shots…I am not particularly computer literate…thanks
