Rev's ask/answer dialogs handle this for you, you don't have to do 
anything. On Mac OS 9 the ask/answer dialogs are modal and block all 
other user actions. But on Mac OS X the standard interface is to have 
dialogs "belong" to and be modal for only one window. Therefore, 
ask/answer dialogs will not allow any other actions in the current 
window, but the user is free to change windows or move to other 
applications. This is expected OS X behavior, and is the reason the 
"sheet" command was introduced.

All windows whose style is "toplevel" will be white, but palettes, 
modeless, and modal windows use the OS stripes by default. To make your 
window patterned, set its style to something other than toplevel and 
don't use any backcolor or backpattern.

Revolution leaves this up to the developer. Set the decorations of the 
stack to change the window behaviors. (Look at the "decorations" popup 
menu in the "Basic" pane of the stack inspector to see the various options.)
