Possible Issue with ckeditor in chrome

Hi there,

i use the latest ckeditor / ckfinder in my ASP.NET Solution (Visual Studio 2010).
I use the ckeditor in an jQuery-Dialog und load the data via jQuery, store the data via AJAX to a WebService.
I haven´t made any changes in the configuration in ckedior or ckfinder (but i think the problem isn´t the ckfinder).
So, i set an breakpoint in the form_load event 1. line.
1. example --> Firefox 4.0 (i think with ff there is no problem)
- I let the site run in debug-mode
- The breakpoint reaches, go on and all ok
- Open the ckeditor in a dialog
- hit the Add Image Button
- hit cancel/or OK when select a image-path <-- nothing appears
- close the dialog

2. example --> Chrome 10.0.xxx
- I let the site run in debug-mode
- The breakpoint reaches, go on and all ok
- Open the ckeditor in a dialog
- hit the Add Image Button
- hit cancel/or OK when select a image-path <-- and here my debugger will reach the breakpoint. So my problem is, why my server goes in a roundtrip. I found that the context isn´t the same context when i will make a roundtrip in normal state, i havn´t any cookie.
- close the dialog

So can anybody reproduce this problem, or is here any configuration that i forgot (but FF does it right and Chrome not imho).

Here are the results of testing with various browsers (latest version):
IE --> no postback
FF --> no postback
Chrome --> Postback
Safari (Windows) --> no Postback
Opera --> no Postback

Regards an Thanks,

L.
