some strange bug is that "show databases;" query in phpmyadmin and in heidi gives different numbers of tables
there are 5 tables viewable by current user
smth
smth_table1
smth_table2
smth_table3
smth_table4
in phpmyadmin they all accessible, but in heidy only first two are present in the list
the version on heidi is 5.1.0.3378
