Today while working with infopath forms i feel sometime when I try to copy and past some text or control across the view or to different location in a same view it never past the content i have copyed. many people do system restart and it work but when i dig a bit its a strange dependency
if you close all your open IE window copy past starts working normally .
Don't know what this have to do with IE . but certainly there is some relation between on IE and info path one more such example if if you make you your IE offline your info path will also get into offline mode .
