Microsoft Word - What to do when Word says "UBitMenu04UK,dotx is locked for editng by Win 8.1 VS8 x64"

Asked By chau do quang on 14-Feb-20 09:41 PM
Sometimes when i save a file (after editing),, the computer screen blink white, saying "not responding" and a small table appears, saying "UBitMenu04UK,dotx is locked for editing by Win 8.1 VS8 x64". Why it does so, and what can I do to solve the problem? Please help.
Many thanks
