I will definitely look at integrating 3 into the next version.#2 doesn't need an option, just simply pass true into that function removePrompt() should work: removePrompt(true,'escape',jqi); should work. Now you can use the regular callback. I may look at changing it to this as it seems more appropriate.As for #1 I will look into getting that to work,.. looks like it will be fun :) Thanks for the code and suggestion!

Although, perhaps the following is a better solution: trap the blur events for the first (if shift is pressed) and last (if shift is not pressed) inputs in the prompt, and returning the focus to the first and last elements respectively.2) If we're talking about the new version, I have modified impromptu to allow a callback when removing the prompt with the escape key: Add the following member to the ImproptuDefaults object (line 22):escape:function() {}Change line 82 as follows: if (kC == Esc) {removePrompt();o.escape();}3) As I mentioned in a comment to a previous blog, the focus option doesn't do anything under IE. Apparently, the focus can only be set after the buttons are visible. I've worked around this by setting the focus in the load function. 1) IE has a document.activElement property, but that isn’t cross-browser.

2) If we’re talking about the new version, I have modified impromptu to allow a callback when removing the prompt with the escape key:
Add the following member to the ImproptuDefaults object (line 22):

escape:function() {}

Change line 82 as follows:
if (kC == Esc) {removePrompt();o.escape();}
