GS105Ev2 password setting limitations

New managed switch purchase to help with network infrastructure, so I am not new to networking equipment, but what I encountered has to rank about a 9/10 of obfusticatedly horrible user interface experience when attempting to change the default administrator password on this cute little beasty.  Nice default admin/password  ... original... I like it...  but more to the point:  

I typically autogenerate strong passwords via Safari and that updates my Keychain of passwords of my electronic pets.  This has worked seemlessly until my encounter with the GS105Ev2, whereby it took the input and upon click of the SAVE button nothing happened.  Like nothing.  No dialog box.  No warning of invalid password.  No clues to improper input.  Nothing.   Okee dokee.   Being concerned that I might be locked out I check my Keychain and it was smart enough to know that nothing happened and I simply logged back in with that really safe admin/password combination and tried to figure out the limitations of this password change.  So, admin/foo works and gives a successful dialog box.   Yippee I am so secure with a three character password!!!!  No warnings of me being a dip$h1T for using such a short password.  Okee dokee...  I change it again to admin/cat ... works like a champ!!!  Yippee!!!!!!   Feeling more secure already.   Try a random alpha-numeric sequence with no special characters and find the only sequence that works is 11 characters or less.  Not 12.  You get no warnings of invalid input so long as both fields match.  Holy $h!T8all$ dudes!!! What is wrong with you????   Did I miss something in the documentation?  I love to RTFM this mother...  

Thanks in advance,
