Try this:
1) Put the attached "autocomplete.e" in your config/hotfixes/ directory.
2) Load it (macro > Load Module...)
3) Do what you do to reproduce the problem.
4) Immediately afterward, go to the SlickEdit debug window and hit Ctrl+X to copy the contents
5) paste that information into a reply
6) Re-load the original <installdir>/macros/autocomplete.e
