When I check out a license from the Zoo, after a while Rhino starts warning me about its expiry:
The problem is that this window pops up under all other open windows, so it looks like Rhino is taking a looooong time starting up. Then after a while I’m thinking, this takes way too long. And find the dialog, click OK and continue to load Rhino.
It’s an annoyance, that could be improved if this dialog pops up over all other windows and/or if the dialog could be disabled, or shown once daily or some such.
