Mmm... that's exactly what I've tried, about 39 times now
I see the difference between objects and themes, but I'm not messing with that.
To make it simple, here's what I've done:
1)install DX
2)unzip theme into My Documents
3)double click the theme's main file...
...when it goes to load, it only loads like one side image (like maybe the one with CPU usage etc.) depending on which theme I'm trying to load.
No other images are loaded, and my desktop looks the same (if not very buggy in action) except for one image.
Wallpapers are not loading, nor are the icons/bars changing anywhere on my desktop like they should.
I make sure I "New Theme" and opt to clear the settings before loading the new theme.
I've even tried, as stated, putting the theme's file in the "Theme" folder in the DX program folder, but it will not show up in the pop-up box when attempting to load a theme, which tells me there's a problem.
So, that's the run-down... can't figure my way around it.
