Unable to attach files to Outlook/Hotmail email

I am unable to attach files in my Outlook (Hotmail) emails.

Problem # 1 - I click "Insert>Files as Attachments" and browse my files. Only a few of my files show up - not all the files that are in the folders I browse.

I have found a very inconvenient way around this: by moving my files into the folders I am able to view. NOT an acceptable solution.

Problem #2 - when I click on the file I want to attach, I get an error message that says "Internet Explorer has stopped working - A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available." Then my email is closed - losing all that I typed! And it opens another blank composing window.

I have these same results whether I try to attach any type of document or photo.

I have done EVERYTHING suggested in these threads and NOTHING has worked:

I have the updated IE 10 version on Windows 7 on my PC laptop

I have the updated Silverlight version

I have cleared all my cache and cookies (which caused other inconveniences as well)

I have reset my internet settings

I have tried InPrivate Browsing

My computer completely optimized, updated, disc clean, defragged, scanned for viruses, etc.

My documents/photos are not open when I try to attach them

I have shut down and restarted my computer

I have signed out and back into Microsoft

I have not changed any settings, other than allowing automatic updates.
