Using XEmacs 21.1 patch level 4, and VM 6.72 an annoying redraw glitch is observed. Open a vm frame on any mail file. Resize the X window (I happen to be using using vtwm on a Solaris 2.6 machine) using the resize widget. Notice that the contents of the window are not redrawn. Move the window using the mouse. Now the contents are redrawn. I'm not sure if it is a VM bug, or and XEmacs bug; hence I send it to both lists. Note: a colleague using the vm version 6.71 from the sumo tar ball also observes this problem.
