nanoGALLERY: error on hoverOut n[r].toFixed is undefined [nanoGallery]

I am getting this error: nanoGALLERY: error on hoverOut n[r].toFixed is undefined [nanoGallery] when using labelAppear, labelAppear75 for thumbNail effects

Can you give me a live URL to check this?

Hi Kris, I just got the same issue like macsupport.
At least in our case the issue can be seen when the CSS is dynamically loaded (async-way) and it happens because on the

var c=jQuery.Color($newDiv.find('.labelImage'),'backgroundColor');

it returns transparent because the browser still hasn't interpreted/loaded the nanogallery CSS.

I guess it's no nanogallery fault in this case but it might help fixing this by adding the possibility to offer a "default" value for the labeImage styling values.

@andrea-sdl many thanks for the update!
I'll implement a fix based on this.

@andrea-sdl a fix is implemented in v5.9.0 but I'm not sure it will always work correctly.
The default value may be incorrect...

@Kris-B thanks for the super-fast support.
I checked the code and now it will surely work, although you are right, it might not work correctly because it will use "black" as default background, while it might be an issue with async loading (and therefore the css is still not interpreted).

Your fix will work, although it will cause some graphical inconsistency when the problem arise (as you noted).

To evolve it even further we could

1. Allow some kind of function to be callable externally so that we can reset G.custGlobals.oldLabelRed etc with the right values (after the CSS has been interpreted).
   I have some ideas on this, maybe I'll try to put them down on code if I got some extra time.
2. Pass a "default" label rgb-color-background in the init, so instead of 0,0,0 (rgb) we have a more consistent fallback in case of errors. This isn't the cleanest solution but it would probably be the fastest to implement.

a workaround is implemented in nanogallery2 (http://nanogallery2.nanostudio.org)
