Glynn,

Disabling set_size() seems to have worked. Below is the output from
xprop.

WM_STATE(WM_STATE):
                window state: Normal
                icon window: 0x3404901
_DT_WORKSPACE_PRESENCE(_DT_WORKSPACE_PRESENCE) = 0x101
WM_PROTOCOLS(ATOM): protocols  WM_DELETE_WINDOW
WM_CLASS(STRING) = "x0", "GRASS 5.0.0pre1"
WM_HINTS(WM_HINTS):
                bitmap id # to use for icon: 0x6400002
WM_NORMAL_HINTS(WM_SIZE_HINTS):
                user specified location: 10, 10
                user specified size: 450 by 400
WM_CLIENT_MACHINE(STRING) = "tekmap"
WM_COMMAND(STRING) = { "x0" }
WM_ICON_NAME(STRING) = "GRASS 5.0.0pre1 - Monitor: x0"
WM_NAME(STRING) = "GRASS 5.0.0pre1 - Monitor: x0"

I guess the question is now,  is the problem unique to my particular
setup or will other Solaris dtwm machines have the same problem?

Let me know if I can provide any more info or testing.

Thanks for your help.
