Make grabber bigger...events difficult to grab?

I am using the scheduler and over the time i have used it have made changes to the units and styles pages.

Now my events are difficult to grab.

It seem like once I grab them they do drop OK.

But grabbing the events seems to be the issue.

Is there some way I can make the event easier to grab.

Perhaps increasing the “grab area”…maybe a style, maybe an xy height?

Can you provide a demo or a link sample where it can be checked?
