monitor the mousemove event

Hi,

I am looking at using extjs5. My existing application used the mousemove event for a component. In the afterrender function I call:

this.mon(this.getEl(), 'mousemove', this.onMouseMove, this, {capture: true, buffer: 20});

This doesn't give any error but it doesn't work either as the onMouseMove never gets called (the 'click' event works though).

Does anyone have a suggestion/solution?

Thanks in advance,

Paul
