assemblies keep getting errors

[Boonaap]

Hi,

I inserted two assemblies in my ASP.net application (in VS 2002). Both the
dll are stored in the root 'bin' folder, they are properly declared in the
page and the codebehind, in web.config following code is inserted:

<compilation defaultLanguage="c#" debug="true" >
<assemblies>
<add assembly="FreeTextBox" />
<add
assembly="DBauer.Web.UI.WebControls.DynamicControl sPlaceholder" />
</assemblies>
</compilation>

and yet I get on an irregular basis servererrors,
"Parser error : acces denied
DBauer.Web.UI.WebControls.DynamicControlsPlacehold er"

It looks to me that i am forgetting something somewhere ....
