Thanks for replying and straightening me out. You know what I think it is? It's a presentation thing. I've been using ImgBurn for months on Win XP Pro P2, and I KNEW that was a "usage" meter, not a progress bar. On XP, when I select the files to include, the "progress" doesn't "track" along the bar then stop....it's simply at the usage level of the files I selected when the window above it closes, and it doesn't "look" like something is happening. All 3 buttons are ready to accept input. I do remember trying to interpret what that actually represented when I first started using ImgBurn (and it didn't take long).
However on Windows 7, the green line starts tracking across the bar and then stops, but the shadowing affects (which are really cool), keep cycling (on the green part only, of course), which gives the illusion that something is still "happening", yet the green line is "stuck" at some % less than 100%. Also, I went back to see if the OK button went from gray to available, and it does, but it's a gradual change that happens while the green bar is tracking, so its state change is kinda lost in the visual affects above it.
I feel like a moron for reporting this, but I guess it was just enough of a difference from what I was used to that it threw me off.
BTW, I noticed this same behavior in BUILD mode when adding a VIDEO_TS folder and clicking the calculator...the progress bar gives the impression that it isn't done, possibly because of the moving shadowing.
Of course, it could also be that after installing a hundred apps from installation files in the last 2 days, that if a progress bar doesn't make it to 100%, something is wrong (even though these aren't progress bars, it isn't really clear what they represent, although I don't recall ever interpreting them correctly on XP).
Thanks again for setting me straight...
