missed keystrokes

It seems that the 'Delete' key is not always handled.
Some of my objects seem to miss the "Delete" key when I enter this key in a rapid sequence.
I tried this on standard Navision objects and experienced that this also happens for these objects.
For example when I run the Item table and go to the field "Vendor No." of the first item record and repeat the following key-sequence 'Del' - 'Arrow Down'- 'Del' - 'Arrow Down' - etc. only some values are cleared.
When I use the spacebar it works OK.

Is this a known bug in Navision?

Thank you for your help.

    I think you are just a little to fast for Navision or your pc / notebook.

    Try doing it in slowmotion, along with the slowmotion sounds people make when they talk.

    Maybe you should practice slowmotion first to be sure you are doinf it right. I recommend shopping in slowmotion... It's great fun, I do it all the time!

    Try 'Edit, Replace' or 'Ctrl+H'. It can save some time :wink:

    Thanks,

    But I have a work-around.
    I thought I made an error in my object, but I was surprised
    that the problem occurred also in standard objects.
    I looks like the DEL-key is handled before the text in the edit-box
    is selected and therefore has no effect. When you type the keys slowly the text is selected and cleared by the DEL-key.
    Clearing the fields using a space or 0 (depending of type) works always.
    That is what I don't understand.

    Clearing with space works because it happens after field gets focus and at that time the text is already selected.

    You are right,

    It looks like Navision does some optimizing after a field gets focus.
    When a field gets focus and the next key in the input-buffer results in an navigation action, leaving the currentfield, a lot of actions can be skipped.
    In 'Pseudo'-code something like this:

    Peek InputBuffer
    If NextKey is Special-Key (like arrow-keys etc.)
    {
    --
    }
    else
    {
    SelectText;
    ReadKey;
    --
    }

    If I'm correct with this assumption calling the DEL-key a special key in this context is erroneous.
