PerformCallback on ASPxCallbackPanel doesn't seem to end

We use ASP.NET controls from DevExpress.

In our application, we use the control ASPxCallbackPanelin different places. the callback is launched "CallbackPanel.PerformCallback (...)"inside the handler ClientSideEvents.ValueChanged.

Sometimes and only when using Internet Explorer, the download bar and form are blocked. We do not receive any server errors - the client simply displays the download bar and does not stop.

Recommended error handling for callbacks is set in our Web.Config as follows:

..

<modules>
     <remove name="ScriptModule"/>
     <remove name="ASPxHttpHandlerModule"/>
     <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
     <add name="ASPxHttpHandlerModule" type="DevExpress.Web.ASPxClasses.ASPxHttpHandlerModule, DevExpress.Web.v10.2, Version=10.2.5.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a"/>
</modules>

..

<devExpress>
     <compression enableHtmlCompression="true" enableCallbackCompression="true" enableResourceCompression="true" enableResourceMerging="true"/>
     <themes enableThemesAssembly="true"/>
     <errors callbackErrorRedirectUrl="~/sites/special/ErrorPage.aspx"/>
     <settings rightToLeft="false"/>
</devExpress>
