1.) if i open up mxed through max to work on material-then open color picker and use the eyedropper to pick a color from a separate window source, everthything freezes up causing me to reboot. (does not happen with standalone mxed or within studio - only when called from max?)
I'm afraid there's no solution for this. Max is waiting for MXED to finish; when you use the color picker, MXED sends a message to Max to get the color of the pixel you clicked on, but Max can't answer because it's waiting. The programs are waiting on each other, which is called a deadlock.
2.) after editing a material through mxed within max material editor and close and save, it brings me back to the last map channel i was on within the max editor. if within that channel i choose "display in viewport", i get an error message saying the image or something can't be found then max crashes.
We'll check this and fix it for the next build, unless it's some obscure "feature" in Max.
