Yes, I fully understand the 'evils' of modal dialogs, but there are times when it is the only option. In this case I am interfacing to a library that has a callback that wants some input (a passphrase) and I cannot just return without the passphrase and I don't know (in advance) if the passphrase is even needed or what the hint for the passphrase is (this info gets passed into the callback). And the callback might be called again if the passphrase is wrong. I may implement this with a subprocess, but then the subprocess itself will need to have a modal dialog. I am only interested a *local* type modal dialog. > > -- Robert Heller -- 978-544-6933 / hel...@deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
