Positive. I even tried using wnd (var for the parent window) too, and it doesn't work.
Here's the code for WndImageEdit.General
code:
<Window Id="WndImageEdit.General" Version="1">
<Position Width="200" Height="180" />
<ChildTmpl/>
<Controls>
<Control xsi:type="StaticControl" Id="lblGenName">
<Position Width="40" Top="0" Left="0" />
<Font><Bold>true</Bold></Font>
<Caption>Name:</Caption>
</Control>
<Control xsi:type="EditControl" Id="txtGenName">
<Position Width="60" Top="0" Left="80" />
</Control>
<Control xsi:type="StaticControl" Id="txtGenNameDesc">
<Position Width="180" Top="15" Left="5" Height="25" />
<Attributes><WrapText>true</WrapText></Attributes>
<Caption>Specify a name for your image. Only used as an ID by you within the script itself.</Caption>
</Control>
</Controls>
</Window>
