Found a proper anwser

        Ext.override(Ext.selection.CheckboxModel, {
            onRowMouseDown: function (view, record, item, index, e) {
                //view.el.focus(); - commented focus()
                var me = this,
                    checker = e.getTarget('.' + Ext.baseCSSPrefix + 'grid-row-checker'),
                    mode;
                if (!me.allowRightMouseSelection(e)) {
                    return;
                }
                if (me.checkOnly && !checker) {
                    return;
                }
                if (checker) {
                    mode = me.getSelectionMode();
                    if (mode !== 'SINGLE') {
                        me.setSelectionMode('SIMPLE');
                    }
                    me.selectWithEvent(record, e);
                    me.setSelectionMode(mode);
                } else {
                    me.selectWithEvent(record, e);
                }
            }
        });

worked for me
