Hi, me again. Actually I thought I'd try FX on my HTPC box running ME and I'm not having luck. My second box is linked to my primary XP box (and the web) via bluetooth stub and it installs fine but kicks up an error saying that it can't activate. The FX on the primary box is fine and functional and this would be build 2.1 but I'm wondering if it's not meant to run on 9x? It seems like it should as it says some features require xp in the setup which to me indicates that at least part will function in 9x right? On my ME box I have WB 4.6, icon packager, theme manager, component tray, object bar, and of course windowFX all succesfully installed as "purchased", and even icon packager gives the "activate" context menu as well as FX but icon packager works fine! Would there be any way to fix this glitch? If I try to click open FX from the component tray it first tells me "explorer has caused an error in user.exe" (first time) and then clicking open FX it says "wfxload has caused an error in unkown", something like that anyway. Any ideas? Thanks..
