If I focus on a user-input box, select what's in it, press delete, and start typing, the first two characters I type will get selected and deleted.

Let's say this is an input box:

Input Content

I put my cursor there:

Input Content |

I select:

|Input Content

I delete:


I type:



c |

cd |

cde |

When I type in an input box that I have selected in, the first two characters are selected and deleted.

    Is this universal in your system, or particular to a certain application? If universal, you may notice in the Keyboard settings under replace text certain combinations are causing the issue. Just a little more info regarding the applications it occurs in or other circumstances would help in offering a solution. Cheers! – bjbk Jun 21 '15 at 23:28

  • One more question, do you have a 3rd party auto-enter application like Text Expander installed? – bjbk Jun 21 '15 at 23:44

    I have seen this bug too. It's too rare for me to figure out its cause though... – William T Froggard Jun 22 '15 at 0:45

    Thank you, you know those boxes are preset how much you can type in them. Is it Adobe form or web based (Java). Also I guess the "Input content" is grayed out. – Ruskes Jun 22 '15 at 2:09

I figured out the answer by myself.

Input boxes in web forms tend to lag a little, and so does my selection. If I select all the text in the input box, dragging my cursor from the end to the beginning, the selected area will lag behind half a second.

That lag is what causes the problem. When I start typing afterwards, the selection is still active, causing it to replace one or two characters if I type too fast.
