In the tree, I select <my database>, <Schemas>, <Tables>, which indicates that there are 62 tables.
On the Properties tab, the first column has a "select all" checkbox in the header. I "select all" and do "Drop Cascade". This completes, but 12 tables remain. Not all tables were selected by "select all", only the first 50.
However, if before I use the "select all" checkbox, I scroll to the bottom of the table list, return and then "select all", "Drop Cascade" does indeed drop all tables.
I'm wondering if there is a setting I can change to increase the default selection or is this a bug?
