Description:
It's impossible to add a Subnet Mask in any Box of "Limit Connectivity to Hosts Matching", since a "/" is a illegal character.

How to repeat:
Open "Users and Privileges", add a User, Key in a IP with Subnet Mask in the Box ""Limit Connectivity to Hosts Matching".

Thank you for the problem report. Verified with 5.2.40 on Mac OS X also.

Fixed as of the upcoming MySQL Workbench 5.2.45, and here's the changelog entry:

The "Limit Connectivity to Hosts Matching" option did not allow an IP with
a Subnet Mask because "/" was considered an invalid character.

Thank you for the bug report.
