ctrl + shit + i kills browser and debug console

[peerus]

When i'm trying to figure out why javascript is not wrking on one page i press ctrl + shift + i to open console. But this kills whole process tree.

I'm thinking that javascript problem can be realated with barcode scanner functions in browser

    //Catch keys
    function enableCatchKeys(edisplayInput, eOnEnter)
    {
        KC_catchKeys = true;
        KC_displayInput = edisplayInput;
        KC_onEnter = eOnEnter;
        //document.getElementById('scanner_status').innerHTML = labelScannerReady;
        //document.getElementById('scanner_status').className = 'scanner-status-ready';
    }
