On my laptop I've exact the same situation. XPize 4.3, IE7 and WMP11 installed. I've just uninstalled XPize 4.3 after reloading but IE7 and WMP11 are also uninstalled. I think this is not yet a problem with XPize 4.6 Beta 2 but it could be if this bug isn't fixed in the past versions. I haven't read the changelogs so I dont know. If it isn't fixed in the past I think it's a must have for the comming release . . . I'm going to install XPize 4.6 Beta 2 in a few minutes, I love XPize; XPero keep on going the good work!
