Not as far as I know. It'd be a nice feature to request though...
Being able to set additional new window properties, including a modal option (to keep users from interacting with other layouts until the new window pop-up has been dismissed) is a feature I've requested before.
Perhaps others would like to navigate to the feature request form and "chime in" ?
The answer from "PhilModJunk" is correct (Thank you!). On Windows, even though no scrolling is possible, the scroll bars appear. On Mac, they do not appear.
Please enter this suggestion into our Feature Suggestion web form located at:
Although it would be easy for me to copy your post and paste it into the form, there are additional questions asked that only you can answer.
