>>This forums does use the master page. However all popup dialogs are all modal dialogs.

 

Saw your post at http://cutesoft.net/forums/thread/32394.aspx. Probably, it applies to a former forum version.
Sorry - misread your post. Thought it was 'does not use the master page'. However, waiting for any reply... 

 

Though, it is my case - usage of master/content pages breaks modal dialog for IE 6. And it is all the same for your forum.

I was able to reproduce this issue at another computer (another windows build, same IE 6 version). BTW - I got error message there as well, but I do not have it at my machine - it may be environment bug.

 

IE7 and FF works fine.

 

Will send screenshots with IE 'about' dialogs and error message. See incoming email - "thread_32394_screenshots"

 

Update: got a mail daemon saying email is not available. So here are full versions you asked for:
