First of all, great job for the optimisation, the last bug I send is corrected.
However, I note two bad behaviour (sorry, I have only bad news those last times...)
* Popup seems not to dimm the background anymore
* Update of deleted widget seems not to work
The first appear today (with the last modifications) but the second was already
present yesterday.
The following program hightlight the second problem. (it's almost the same proggy as
yesterday...)
A little 'coucou!' button have to appear/disappear in the same way as the launcher.
But it doesn't and is always displayed but not binded...
If I replace the create/delete process by a size=size/size=0 one, it works, then maybe
the problem is about it's grop node that isn't deleted...
Maybe this is of some help...
