Click on the Hello World button and try dragging around the window. It will attach itself to the cursor *after* you released the mouse button not while it is pressed.

This bug is only showing up on Mac OS X. I works on Windows and Linux.

Reproducible: Always

Steps to Reproduce:
1. open http://extjs.com/deploy/dev/examples/window/hello.html on a Mac
2. try dragging around the window
Actual Results:  
The window will attach itself to the cursor *after* you released the mouse button

Expected Results:  
The window should attach itself to the cursor while the mouse button is pressed.

I can reproduce this on OS X 10.5.2 with Firefox 3 RC 1, but not on
Windows (XP) or Linux (Kubuntu 7.10).

I can also reproduce with Camino 1.6 and a recent Camino trunk nightly
(both of which use Cocoa widgets), but not with Firefox 2.0.0.14
(which doesn't use Cocoa widgets).

All of which strongly suggests this is a Cocoa widgets bug.

But I don't know how serious it is (how often it will be encountered).
If possible, please give me examples of sites where this problem
occurs.

I can confirm your test results.

It seems like the objects you drag have to be some kind of "heavy" to fail proper dragging. Simple objects can be dragged (http://demo.script.aculo.us/shop), even using the extjs framework.

I'm still looking for another test case. I'll let you know.

I found another site which uses ExtJS.

Try dragging around the login window...

This is a regression from Firefox 2, but not sure it's wanted for 1.9.0.x instead of just picking up in 1.9.1...

Doesn't really meet the "wanted" criteria (security, stability, regression from maintenance release) for 1.9.0.x. However, we'll look at a reviewed and baked patch.

As best I can tell this has been fixed.
