The affect on a transparent template with this module really does give the website a really different feeling.
Really happy with the end result.
I have used the ticket system twice and had replies back within 24 Hours.
The only issue I have had over the last 2/3 releases is that during the install it does not install the Zend framework so it will not work unless it is present, then there was issues with installing 2 parts of the Zend framework but this now seems to be resolved.
once installed you need to activate it by going to you plugin admin.
It does show transparent png files correctly, but they will only work with certain transitions due to the way the transitions work. You will need to test different settings until you get the desired results.
I read some negative reviews from people about it not working and I couldnt get it to work at first either but it was more to do with getting used to how 1.6 works in relation to 1.5, once I realised this I got it to work.
So a little patience would be better spent before writting a bad review.
