I want use 'save as' to save the document under another name, I get a white screen and I can't save it.

Hi Inekev,

In order to get this white screen issue resolved, you need to make certain changes to the application's preferences settings.

Here is a forum thread "Save As" box is blank  where similar issue has been discussed and resolved.

You may follow the suggestions and let us know if that helps you too.

If it doesn't, then we would look into this further.

Regards,
