I spoke too soon. I'm really tearing my hair out here. Each version has its own problems, but they both sort of stop working after a while and need to be restarted, and sometimes I completely need to reboot.
The same theme displays somewhat differently in each different version. In the newer version, although I have edited certain items, they just do not display as edited. I think the newer version is a bit more stable and I'd like to continue using it, but it simply won't let me edit certain things. Or, what I mean is, I edit them, but they do not change when I test the theme. Does anyone have any idea what could be wrong?
Also, the new one does not remember where to save to or open from from one reboot to the next.
Thanks,
Ellen
Edit: Fortunately, I am seeing that when I try the theme in Windows\Resources\Themes as a theme, all the edits do show, but it is utterly maddening to work this way.
The theme compiles the same in 1.5.0.3 and 1.5.5.9 as the backend hasn't changed at all. So there's no reason why one should have different results from the other. What are you trying to edit exactly?
