If you use latest version of jquery (1.4.3) in your theme instead of the default one, admin menu toggle does not work properly. (The admin panel does not show up anymore after the first time you hide it)

By using firebug I found out that a "display:none" property is added when the panel is closed. That property is not removed when trying to switch back to display the panel.

I reproduced the issue in FF and Chrome, I could not reproduce in safari.

I fixed it by adding .show() in the includes/admin.toolbar.js file, line 130:

<?php
  
$('div.admin-blocks', toolbar).animate({width:'260px'}, 'fast').show();
?>

Tested and working on 7.x-2.0-beta3 (change line 136 instead of 130). Thanks!

Confirmed, same issue here on latest dev version.

When first hiding the bar, Drupal.admin.toolbar runs $('div.admin-blocks', toolbar).animate({width:'0px'}, 'fast', function() { $(this).css('display', 'none'); });. Note that display property is set to 'none' at the end.

When clicking again on the button, the bar reopens by running $('div.admin-blocks', toolbar).animate({width:'260px'}, 'fast');. Note that the display property remains unchanged, so it doesn't display. It can be fixed with any method changing back the display property to 'block'.

Patch attached.
