Thanks to Mike for the tip that got the X4 upgrade in testing working for me. I'm a happy camper again.
I also noticed that Lyx was removed during a recent upgrade in "testing". I tried to reinstall it but found that it requires libforms0.89 Since Lyx is (in my opinion) one of the best document editors around, I was wondering if anyone else had worked around this problem. libforms0.89-bin and libforms0.89-dev are both listed in the online list of packages, but just plain libforms0.89 is missing. I cannot apt-get install any of the 3. Suggestions? Thanks in advance Glen
