Using WaveLab Elements 10.0.40 on Windows 10.
Try opening any audio file with WaveLab, directly from the system’s file explorer or via startup dialog (it doesn’t work from inside the app file tab). After opening the file, click on the File tab. It must show directly the File Info panel - if it opens another panel, switch to the File Info panel, close WaveLab and open the file again.
In my computer the metadata box overlaps part of the controls to the left, as shown in the attached screenshot.
Not an important issue, but nonetheless a bug.
