Hello Raeshawn,

It would help if you explained what is the action that causes RadWindow to not stay on the screen, instead of leaving us guessing.

At this point, I can assume that the issue is with server events/actions invoked from the RadImageEditor, because it is in the ContentTemplate of the RadWindow. This article explains how to use AJAX in this case: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html.
The essence, is that you need the update panel in the ContentTEmplate, so that RadWindow itself is never disposed:

<telerik:RadWindow ID="RwImageEditor" runat="server" Animation="Fade" AutoSize="True"

Modal="False" VisibleStatusbar="False" Title="Edit Photo" EnableViewState="false"

ShowContentDuringLoad="true" VisibleOnPageLoad="false">

<ContentTemplate>

<telerik:RadAjaxPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default" EnableAJAX="true">

<telerik:RadImageEditor ID="RadImageEditor1" runat="server"

OnClientImageChanged="imgEditorImageChanged">

<Tools>

<telerik:ImageEditorToolGroup>

<telerik:ImageEditorTool CommandName="SavePicture" />

<telerik:ImageEditorToolSeparator />

<telerik:ImageEditorToolStrip CommandName="Undo" />

<telerik:ImageEditorToolStrip CommandName="Redo" />

<telerik:ImageEditorToolStrip CommandName="Reset" />

<telerik:ImageEditorToolSeparator />

<telerik:ImageEditorTool CommandName="Crop" />

<telerik:ImageEditorTool CommandName="Resize" />

</telerik:ImageEditorToolGroup>

</Tools>

</telerik:RadImageEditor>

</telerik:RadAjaxPanel>

</ContentTemplate>

</telerik:RadWindow>
