David,
When mine did that, I went to a local electrical supplier and got 4 metal
clamps that are designed to hold small wire to walls (ie: phone wire during
construction) and used the existing screws with these "tabs" to hold it in
place.  Probably available at Radio Shack.   I'm not sure of a good way to
describe them but I'll try.  1/2 " wide, 3/4 " long, flat on the end with the
mounting hole, and curved on the other end to originally hold a 1/8" wire
against a flat surface.  They have worked wonderfully for me and I never give
them a second thought.  If your the type that recognizes that pop cans make
good shim material this should solve your problem.  On the other hand, I
don't know where to get German ones and that might bother the purists in the
group :-)
