Need a good graphical UML diagram-making program

[Stronzo]

I'm trying to make some UML diagrams and it's a big pain in the culo to draw the boxes by hand. Anyone know of a good program that could help me out?

If you are running Linux and have X installed, Dia is a good program. It does flowcharts, UML, ERD's, Circuits. etc. I don't know any free programs for windows that can do this. Good luck.

I think rational rose is good for that. Works on Win9x.

When using windows i use visio for network diagrams, on linux i've tried http://www.omnigroup.com/applications/omnigraffle/ and http://www.research.att.com/sw/tools/graphviz/ - both pretty good.

Ya, thanks for the input. I'm on Win2k. I'll have to look into finding copies of those programs you guys mentioned. Any ideas where to start looking?
