Motorola Droid 4 :: Cannot Save Email Attachments?

I cannot save attachments to the phone or to my external SD card, which is not encrypted. I have no Exchange 2010 security policies blocking attachments. ICS is not set to encrypt anything. I use NitroDesk TouchDown, which also has no saving restrictions or encryption set.I go through the process of Save, or Save All, and try to save, or create a new folder in which to save, and then click to save the file. I can see the new folder I created, but there is never a file saved. Rebooting does not make it show, nor does dismounting and remounting the SD card.Probably related to the above problem, if I have an email in TD with an attachment, for example a DOCX file, I can open it in Documents to Go, but if I do a Save As from there, it will not let me save it anywhere. If I use Docs to Go and create a new Word doc, I can save it anywhere I choose, so it is as though TD will not let me manipulate my attachments.
