"Output window Follows selection(Toggle)" command stopped working after 4.1.1

Ok cool.Thanks!

Hey Christian,
I'm using a version of the same code and am getting an error as well.

Error: Object reference not set to an instance of an object.
(Track Output Folow track selection line 27)

I'm stoping all soundflow commands and restarting the script and woks again for a wile.

I'll put this on a Help/Issue if you prefer

Thank you

var lastFocusedTrackName;

function main() {
    try {

        var newName = sf.ui.proTools.selectedTrackNames[0];
        if (newName === lastFocusedTrackName || newName === undefined) return;

        lastFocusedTrackName = newName;

        if (sf.ui.proTools.mainTrackOutputWindow.invalidate().exists && sf.ui.proTools.selectedTrack.outputWindowButton.value.invalidate().value !== 'open' && (newName.indexOf('_MUSICA') == 0 || newName.indexOf('_FX') == 0))
    sf.ui.proTools.selectedTrack.trackOutputToggleShow();
 
 
    //sf.ui.proTools.selectedTrack.trackInsertToggleShow({
//});    

    } catch (err) {
    }
}

function runForever(name, action, interval, timeout) {
    var now = (new Date).valueOf();
    if (now - globalState[name] < timeout) throw 0; //Exit if we were invoked again inside the timeout

    globalState[name] = now;
    sf.engine.runInBackground(function () {
        try {
            while (true) {
                sf.engine.checkForCancellation();
                globalState[name] = (new Date).valueOf();

                action();

                sf.wait({ intervalMs: interval, executionMode: 'Background' });
            }
        } finally {
            globalState[name] = null;
        }
    });
}

runForever("isScrollToFocusedTrackRunning", main, 500, 5000);
