Using a 6.1 theme on 6.5.3?

[cenozoite]

I notice that if I apply an older WM 6.1 to my 6.5.3 device, I get the old style popup/context menus where all the options appear on one screen, rather than the newer, larger, more "finger friendly" menus which require scrolling up and down to see all options. I like the old-style ones better.

Unfortunately applying an older theme also seems to have the side effect of messing up some of the icons on the bottom menu bar so that they either don't display at all, or display incorrectly. Is there any way to cause ONLY this old-style menu change to occur, without messing anything else up? Either through a registry edit or some other way? Alternatively, is there a way to fix the bottom menu bar on 6.5.3 when a 6.1 theme is applied?

I haven't done any theme editing before so if anyone could provide any assistance it would be greatly appreciated, thanks...
