CSS Flyout problem with 1.3.0.1

Hi, I just have found a problem with modules CSS Flyout from DrByte.
I used it on Zencart previous versions, 1.2.x, and it was working very nice.
Now I have this problem:

I've installed it in a clear version of 1.3.0.1, activated the css categories box and disabled the standard categories box.
It seems works correctly, except for the time it needs to show the items when the mouse cursor pass over one parent category.
It appears really slow. The item selected need a very long time, differently from the previous zencart version, to show the mouse hover status, and to draw the sub-items.

Does anyone found the same problem?
I tried to check css, and I have seen it's completely different from previous, conseguently of the restyling of the template system. Is it possible it depends from these modifications?

Thanks,

Hi, I'm auto-answering me...

the problem depends from the classic template default, I done a new template, using template_default as source, and now everythings work fine.
Maybe there was some conflict in classic template, cause it uses old code, I think.

Bye,
Max
