Thanks for the lack of help guys......

 

Anyway I have solved the problem. A week off helped and came back with fresh ideas.

 

Remember that file blank202.png that was being downloaded 90+ times, well I thought why dont I change it to a gif!

I found there was already a gif of that filename already that was a third the size of the png.

So i edited

 

Scripts\IE_Loader\Loader.js and changed blank2020.png to blank2020.gif

 

and now its ultra fast again!

 

So 2 questions.

1. Why are using a png and not the gif.

2. Can you change this in your next release so I dont need to keep fixing your file?

 

Thanks
