If I change the ‘view’ to make the tracks smaller the mute/solo buttons on each track disappear. But I cannot expand the tracks out again to show the buttons?
If I open the mixer board instead it will open but as soon as I go back to the tracks window the mixer board disappears and cannot be found when I minimise the tracks window?
I am the developer at PortableApps.com for our package of Audacity.
It uses the official release zip version as mentioned by steve: All we’re doing is saving the “Portable Settings” folder between launches, and updating paths as needed between launches. We don’t modify Audacity itself in any way.
With that said, I’m not able to reproduce the issue you’re describing, using either the official release zip or the PortableApps.com package. Try using the “Track Collapse” button to expand the Track Control panel, and Windows’ built-in window-switching keyboard shortcut Alt+Tab to access a window that is hidden by another.
