I have this bug since the first Version of Expression Web. Meanwhile I even changed form XP, to Vista to Windows 7. I tryed with Expression Web 1,2,3 and 4. It is there with all the new installations and versions. I did not have it in Frontpage 2003. I hoped that it will be gone with the latest Version. But no - nothing. I browsed all previous entries in forums. No solution. I work with it a while and suddenly the undo function is messed up. It is very anoying to work on a project and be put back 10 Steps pushing the Undo-Button instead of 1 step.
Repro Steps? (N/A for Suggestion)
