Transparency

I am having the same problem with transparent GIF overlay tiles...

The problem occurs in IE6 and IE7 rc1 but not in FireFox. I suspect it is due to the custom filter that is applied to the containing element (tile) to support opacity. Firefox and IE use different approaches. If the opacity filter is not going to work in IE, due to an IE limitation, than the VE script for tile overlay handling should not use it when the user specifies fully opaque. That way we can at least render transparent GIF tiles at full opacity. I hope this gets resolved soon as this is a major flaw with the current version.

We were hoping that v4 would solve the weird gif and png transparency problem in IE7...

We never saw this problem in FF.

Is there a timeline for a fix? By chance, do you have any release notes with bug fixes listed?

The 3D implementation looks awesome.

I have fixed this issue, it's to do with the Alpha Transform MS use to load our custom tiles.
The full code and explanation can be found here on my blog.

Let me know if anyone needs any clarification.
