Brake fluids

Any problem w/ mixing Dot 3 and Dot 4 brake fluid? I know Dot 4 is rated for higher temps. I just replaced the master cyl. and filled it w/ recently purchased Dot 4. Then I realized that I already had Dot 3 in the remainder of the system. See any problems with that?

You can wish in one hand and crap in the other.
See which one gets filled first.

From what I understand, DOT 3 and DOT 4 are ok, but never DOT 5.
