Sorry it doesn't work for you - such things can really frustrate one.
As a test, I just now did a test that went as follows: (1) I wrote a junk letter in Word and saved it to the 'desktop'; (2) then I right clicked on the TM icon in the tool bar and selected 'back up now'; (3) after it quit doing the audible action, I double clicked on my external 500 GB HDD that I use for backup, and in the screen that opened from the backup drive I clicked on the 'desktop' icon in the left hand column and the letter I made in step (1) above is the very first item in the middle column. Clicking on it brought it to the screen for any further action.
Also, another method is to click the backup drive, then selecting the backup file shown, then 'users', then 'home' (my name or whatever name given), then 'desktop' and the file I saved is located.
I tried to include an attachment of a screenshot of it, but it wouldn't upload.
Not sure why you are getting the 'crash' you describe, nor why my method worked for me.
