- install Mp3tag v3.05a - Beta, standard installation, as Administrator
- import tag data from a text file
- all functions on the tool bar are greyed out and inoperable
- if Mp3tag is closed, it remains in Task Manager and cannot be reopened until killed.
- the MP3tag context menu still works and performing an "Export" returns functionality to the tool bar
After reverting to v3.05, the problem does not occur.
