thanks pantera1989... i know the hover mode thingy but thats not the problem i am facing... hover mode is in browser mode, but during conversation, i should be able to highlight my text by default right? (i can highlight the text before, but now suddenly cannot)

not highlight text as below, but highlight the text entered in the white textbox...
i think this happens after i uninstall several applications, which i had forgotten which one... there is also a problem/bug with application named scim being uninstall which will cause Fn and Shift key to become "unsticky", thus am wondering is it the same case here...

thanks in advance
