CATIA V5-6: How to report bugs?

Hi Everyone,

Does anyone know how or where to report Catia V5 bugs? Is there some customer support mail, website or any other way to send feedback to Dassault?

As an example - I have found a bug, where if you have a Macro with a designated icon in a Toolbar and Accelerator (hotkey shortcut), and then you rename such macro with 'Tools -> Macro -> Macros -> Rename...' it essentially breaks your preexisting shortcut. The shortcut still tries to call a macro by it's old name, but such macro does not exist anymore.

As my experience in Catia grows through the years, I tend to gather more and more findings about buggy behavior and I would like to share them in a proper way, so that these issues could be addressed in future updates.
