Now is a good time to upgrade to ElPack 4. Purchased and downloaded new package. Installed it using their new “easier to install” package. It did deletes first of all possible conflicting results, but still didn’t work for me. I had to use my self-developed install again, and that worked (see April 19).
Check the other ElPack bugs that I had to patch myself. The Inplace Editor (May 10) works nicely now, and selecting additional blocks of entries with the Ctrl and Shift keys now works okay (April 13, April 19). That is nice! No more customizations to ElPack required on my part for now.
