After opening a window through key inputs and then typing in a search box, all non-alphabet keys stop working.
Replicate:
1: Open any NPC window using DialogKeys
2) Type in any search editbox (ex: default bag search)
3) Try to use any non-alphabet key (ex: escape, arrow keys, modifiers)
This issue is present with DialogKey being the only addon enabled, and using the newest 1.7 version. The easiest thing to replicate the issue is using the search box in the default bags, but its happens with any searchbox (my mail addon and vendor addon).
