Problem with the context menu in IE7

Hi

We are experiencing some problems with the context menu in IE7. The problem occures when you have sub menus, example 3 levels.

We experience two problems:

1) The sub menus are not correctly positioned
2) The height of a group of sub menu items CANNOT exceed the height of the parent group of menu items/menublock. Example: If you have five top level menu items with a total height of 100 pixels, sub menu groups cannot exceed this 100 pixel height.

We have tried to narrow down the problem, and think it's a problem either with the window.createPopup() method in IE7, or a problem inside fckpanel.js.

This problem is easy to reproduce.

Inside fckpanel.js, try to change:

      // Second call: Show the Popup at the specified location, with the correct size.
      this._Popup.show( x, y, iMainWidth, eMainNode.offsetHeight, relElement ) ;

to

      // Second call: Show the Popup at the specified location, with the correct size.
                                var tmpHeight = relElement ? 1500 : eMainNode.offsetHeight;
      this._Popup.show( x, y, iMainWidth, tmpHeight , relElement ) ;

I.e. set the height of the menu to 1500 pixels if it's a sub menu. You will see that in IE7, the sub menu is displayed with the same height as the parent group of menu items.

We haven't figured out exactly why this happens, but it may be related to the context where the window is created, i.e. the line

this._Popup   = this._Window.createPopup() ;

at the top of fckpanel.js.

If it's not possible to use window.createPopup in IE7, it would be nice to have an alternative.

Thank you
