CANNOT SAVE FILE

[jademan]

Hello
Every time I finished a recording I try to save it but although the SAVE box prompts up no letters could be typed in.
This happens in usual file saving in Audacity file or an MP3 file.
This only happens recently but there was not any problem for the past 2 years.
Please give your advice. I appreciate it.

Do you have an oriental version of Microsoft Windows? Your issue looks very similar to this post: Freezes when keying in Japanese
