Back in Feb., Microsoft NZ made the Media Center theme available as a download. I grabbed it, never installed it. Yesterday I installed it. Works great. One problem: Since installing it, I cannot save ANY desktop themes. If I go into Display Properties | Themes, it says "Modified Theme". But if I click Save As and browse to wherever I want to save the theme, and click Save, the theme is not saved. I can switch themes, customize themes, etc. Everything else appears to be operating properly. But I cannot save the dang things -- nor is there an uninstall option for the Media Center theme. I tried manually removing the theme, but to no avail. Ran SP2 on a lark, didn't fix the problem. Installed StyleXP and Stardock OD WinBlinds; no effect on the problem. Googling every which way has not produced a single example of a "can't save XP themes" problem. Any takers? Thanks!
