Hello Dale, Regarding the PNG transparency problem, we found and corrected it in version 1.03.16.
We sent you the 1.03.17 version by mail and will make it available for download very soon on our website.
Do not hesitate to come back to us if you have any problem with this new version. Regards.
Hello again Dale,
Thanks to the credentials on your website, we managed to track down the problem, which is now corrected. It looks like the version of IIS you're using is at the root of the problem for png files. In order to confirm this, could you tell us what version of IIS you're using and what .net framework your website is running under. Thanks for your feedback. Regards.
Our DEV system that you were on is IIS version 6, running .NET 2.0.50727.
Our Production system, which didn't work with the .16 version and was not tested with the .17 version of HtmlMapMaker, is running IIS version 7 with the same .NET 2.0.50727.
