Can this be done in real-time without scripting a new cellblock? It would really help with one of my projects (a multiplication table interface which allows scaling of the traditionally 1 - 100 values). The sizes of the rows and columns can be set, so you can see all the numbers in the cells, but I wind up using a really small font to be sure all the #s are visible. Not very viewable on a projector then.
Perhaps there's a message I overlooked? I suppose the same issue goes for number boxes too. Some kind of list of the system fonts --> Max object font code (font, style, size) would be handy. If scripting is the only way, that's fine, but a message is simpler.
