When selecting [No] button on the confirm page for dropping table/s, the resulting display is misleading since no query should be executed when [No] is selected.
The output displayed is:
Your SQL query has been executed successfully
Running phpMyAdmin - 2.11.3deb1ubuntu1.1 - on MySQL client version: 5.0.51a on Kubuntu 8.04
Fixed in subversion, thanks for reporting.
