Mike,
Are you using VARCHAR as the data type in the table definition (table 
edit mode: Text [VARCHAR] )?
If so, what is the "Length" set to at the bottom of the table edit 
dialog for the field?
In the form edit mode, what is the "Max Text Length" property for the field?

Note that these two lengths can be different.  My version has other text 
data types, such as Text[ENUM], Text[SET], Text (fix) [CHAR]. I am not 
familiar with any of these, but if your database is set to any of them, 
it may be the problem.  I believe VARCHAR max is 255 characters, but you 
can limit that with the length settings in Base tables & forms.  I just 
checked one of my forms and discovered the limit for my "Notes" field, 
which is 255 characters max, is set to 0 (zero).  According to the help, 
this property setting gets the length from the database (MySQL?) as long 
as it was never changed (set, or defined).

Note that I am using MySQL 5.5.29 under Linux 3.2.29 and LO 3.6.7.2 at 
the current time.  I do not have this problem with my numerous 
databases, nor did I have it with previous versions of MySQL or LO. I 
have always been able to add to a text field up to the 255 character 
MySQL limit, no matter which record.  When I get to the limit, Base will 
not allow me to enter any more characters until I delete some elsewhere 
to make room for the new characters.  That is better than getting a 
MySQL error when the record is saved.  So, it should work for you.

Hope this helps.
Girvin Herr
