Hi, here’s the problem.
For LibreOffice ver 5.0.4 x86 on Win 7 x64:
I’ve tried both MS New Changjie for Chinese and Google Japanese input methods, both showing the text outside the search box only and they failed to appear inside the box after confirming the text for entry.
Entry into the cells was normal.
Reverted back to LibreOffice 5.0.0 x86 version, it became normal again. That’s my solution.
I’ve uninstalled 5.0.4 now.
