I've written lots of these filter procs (my software uses hacked Standard
File more often than the vanilla version, truth to tell) and I've never
seen these problems, so I have to think your filter proc is in error.

Most likely you are returning true when you mean false and vice versa;
if you return true on keyboard and mouse events that you aren't handling
yourself, you'd get the behavior described above.

You're welcome in advance; hope this does the trick for you.
