Nop 2.1 - IIS 7 several strange bugs since migration from IIS6

Hello,

Yesterday, I migrated from Windows 2003 and IIS 6.0 to Windows 2008 R2 and IIS 7.0 and I now I have many problems I had not before (the database did not change - SQL 2005 - but 2 languages are activated).

For example, this one https://www.nopcommerce.com/boards/t/11482/20-button-savecontinue.aspx?p=2 that I can solve with script proposed by mb.

Another strange problem is the RichHtmlEditor behavior because when I validate my changes , all links are transformed and disabled. For example :
the following text "<p>Cliquer sur la pastille de couleur pour atteindre le produit désiré.</p><p><a href="#3453287233000"><img alt="" src="/ventes_lbd/images/mercerie/prima/fils/723300_Nuancier.png" /></a> <a href="#3453287233017"><img alt="" src="/ventes_lbd/images/mercerie/prima/fils/723301_Nuancier.png" /></a><a href="#3453287233024"><img alt="" src="/ventes_lbd/images/mercerie/prima/fils/723302_Nuancier.png" /></a> <a href="#3453287233031"><img alt="" src="/ventes_lbd/images/mercerie/prima/fils/723303_Nuancier.png" /></a></p>

is transformed like this

<p>Cliquer sur la pastille de couleur pour atteindre le produit désiré.</p><p><a href="#3453287233000"><img alt="" src="/ventes_lbd/images/mercerie/prima/fils/723300_Nuancier.png" /></a> <a href="http://srv-vap/Ventes_LBD/Admin/Product/Edit/3881#3453287233017"><img alt="" src="http://srv-vap/ventes_lbd/images/mercerie/prima/fils/723301_Nuancier.png" /></a><a href="http://srv-vap/Ventes_LBD/Admin/Product/Edit/3881#3453287233024"><img alt="" src="http://srv-vap/ventes_lbd/images/mercerie/prima/fils/723302_Nuancier.png" /></a> <a href="http://srv-vap/Ventes_LBD/Admin/Product/Edit/3881#3453287233031"><img alt="" src="http://srv-vap/ventes_lbd/images/mercerie/prima/fils/723303_Nuancier.png" /></a></p>

All links are replaced (except the first) and all href links are pointing to admin editor.

Does anybody else have this issue? Do I have to migrate back to IIS 6 ?
