I did some investigation, and having one "click" select feature
control and one "hover" select feature control on the same layer
works. The simplest way is to activate the click control after that
with hover control. If done the other way around, then
hoverControl.handler.stopClick = false must be done.

This might still not work as you expect it to work because onSelect()
of the click control won't be called when you go over a feature and
click on it. But in fact it makes sense that onSelect() isn't called.
You move over the feature, it gets selectetd, so clicking on it does
trigger onSelect() because the feature is already selected.

If you tell me more on what you want to achieve, I may be able to help
you further. Sorry for taking so long to go back to you on this issue,
but I was busy with other stuff.

Cheers,
