ok... this is what i think the problem is... just use this as a scenario, as the filenames may be different. there is a file in your windows folder, longpressendkey.lnk or something like that and its possible the .lnk the app uses is named differently. like the rom may use longpressendkey.lnk but the app uses longpress_endkey.lnk. so to be 100% sure what file your rom uses,
1) uninstall the anastasia endkey app
2) go to /windows and find the file similar to longpress.lnk, longendkey.lnk, longpressendkey.lnk, etc

this controls what happens when you hold the end key. once you find this out, you can reinstall the app. the go back into windows and see which file the app adds for the longpressendkey.lnk (or similar). once you find this out, all you need to do is rename the .lnk file. i hope you understand this lol. let me know if you need more help, but i truly think thats why its possibly not working for you...
