Helloi, I'm using ver. 6 52 of WavePad Masters Edition. I don't recall having this problem in the past. Specifically I have downloaded several tunes from Spotify and edited them in to one large continuous music file using WavePad. Most of these created files are from 1-2 hours long. They play fine. But when I try to edit these large files WavePad will only allow editing 5 to 6 minutes of these files at a time. What am I missing. Thank you for your help. Bob
