i'm using ver 3.3 and have downloaded and installed a "database explorer" component. and now, when i want to add column to the recently created table (it's also applicable to creating a new table with the same /described below/ column parameters) i've got an exception: "Unable to format a command: alter table...".
the parameters were: name - doesn't matter, type - "char", size - "20", scale - empty, default - empty, unique - not, null - yes, index - not, check - not.
if i set default value, it seems to be ok (but i don't want the default value).

also to be a problem: when i wrote a default value in a different language, i've got a trash in the column properties.
