Editing a date field crashes

I'm trying to edit a date or datetime field in the Data grid page, but pressing enter or double clicking on the field causes HeidiSQL to crash.

My version of HeidiSQL is 8.3.0.4694 64bit.

One of the fields is setup as a datetime with a default of 0000-00-00 00:00:00. This is in an InnoDB table if that matters, with a collation of latin1_swedish_ci.

I can highlight the box using the cursor keys. It doesn't matter whether the field has an existing date (e.g. 2010-04-05 18:10:01) or if it is a date (no time) field. It's not specific to that table (I've tried other similar tables with date columns).

Timestamp fields seem ok. Date/datetime fields in MyISAM tables work ok.

Interestingly enough, in the same database, datetime fields in InnoDB + utf8_general_ci collation is ok.



So just to summarise after testing against other databases / tables:

One particular database, with a table set to InnoDB + latin1_swedish_ci.
Timestamps are ok, but date and datetime editing causes heidisql to crash with:

Other local databases with this combination seem ok. I've already tried to optimize/analyse/recreate this table.

Strange?
