Unfortunately, the solution to my problem does not work. My original

This apparently is a bug in Solaris. (Bug id 1222114) Sun has a
workaround listed on their SunSolve web page. But the workaround
doesn't solve the problem. Sun says that the problem can be fixed by:

chmod 0555 /usr/dt/bin/dtsession

But a close reading of the bug description reveals the following

> This workaround does'nt work at the customer site

And it didn't work for me either. One solution is to use xlock instead
of the CDE screen lock.
