How-To-Repeat:

1. Copy and execute following sql-script in mysqlcc SQL window of some test db:

############################
DROP TABLE IF EXISTS suser;
CREATE TABLE suser (
  uid double(32,0) NOT NULL auto_increment,
  username varchar(100) NOT NULL default '',
  password varchar(64) default NULL,
  PRIMARY KEY  (uid),
  KEY username (username)
) TYPE=MyISAM;
INSERT INTO suser VALUES (155,'abc','abc');
INSERT INTO suser VALUES (156,'def','def');
INSERT INTO suser VALUES (157,'xyz','xyz');

SELECT * FROM suser WHERE username = 'abc';

# update password in grid from abc to 123 --> 3 rows affected! (in fact all rows are affected)

# select single entry and press delete record button in toolbar --> 3 rows deleted! (in fact all rows are deleted)
############################

2. update password in grid from abc to 123 --> 3 rows affected! (in fact all rows are affected)

3. select single entry and press delete record button in toolbar --> 3 rows deleted! (in fact all rows are deleted)

4. re-run script with primary key column uid of type int and problem does not occur.
