    I cannot reproduce this problem. Please post detailed steps how to reproduce it.

    * What exactly are you doing after opening the entry editing window?
    * What is the initial content of the edit field?
    * What are you entering?
    * When are you pressing Ctrl-Z?
    * Are you showing or hiding the contents of the field (asterisks / dots)?
    * Which .NET framework do you have installed, or are you using Mono?

    Thanks and best regards
    Dominik

    I was now able to reproduce the problem.

    The good news: KeePass 2.05 will not throw an exception when pressing Ctrl-Z.
    The bad news: Making Ctrl-Z work correctly requires a custom implementation of an undo buffer for secure edit controls. KeePass 2.04 currently does not have such a thing (in 2.05 the undo functionality will be disabled). I'm therefore moving this report to the open feature requests.

    Thanks and best regards
    Dominik
