Power2Go 7 with latest patches running.

I've noticed a pattern here on burning discs. First of all, I have two different CD burners and this occurs regardless of which one I use.

I burn a disc and DO NOT close it. A few weeks later I put the disc back in to add more files...but P2Go doesn't refresh the disc. I hit Refresh icon...nothing.

I can see and access the disc fine in Windows Explorer. I am running Win 7 with all the latest updates.

Why doesn't the app detect and allow me to add more files...doesn't even see the previous session(s).
