Description Diederik Huys 2019-10-12 16:31:20 UTC

Every time I try to start a new database, I edit the grammar. While entering any data (usually I start with articles), the window freezes and CPU goes to 100%.


STEPS TO REPRODUCE
1. Start a new database
2. Start editing the grammar of any language
3. Enter data (or just click some buttons)

OBSERVED RESULT

After 3-10 clicks or keypresses, the application becomes unresponsive and must be terminated.

EXPECTED RESULT

No crash.
