ProcessLevelControl issue after LSF 9.0.1.10 patches

We applied some LSF patches to our 9.01.10 and after that have problems with PR36.  Customers can add the form, but if they try to add a new line to an existing form it's like the keyboard isn't working any more, they can't type anything onto the new line.  I found that removing the Security Class on the PROCLEVEL element group solves the problem, but of course we can't do that.  Has anyone found this problem and solved it?
