After installing Database toolbox, and configuring Data Source to an ODBC MySQL server using Database explorer app. I get a long set of error messages when I click on Connect.

Here is a short initial set of error messages that goes on for many lines:

Warning: Error occurred while executing the listener callback for event ConnectRequest defined for class
dbgui.internal.ToolStripDisplay:
Error using figure
Cannot set DockControls to 'off' while WindowStyle is 'docked'.
Error in dbgui.internal.ConnectDialog (line 33)
            this.Figure = figure('DockControls','off',...
Error in dbgui.internal.dbSession/attemptConnection (line 1171)
            dbgui.internal.ConnectDialog(this,dsName,driverType);

I did solve the problem by removing one line of code from my startup.m file:

addpath(genpath(userpath)) % add subdirectories to matlab userpath
% set(0, 'DefaultFigureWindowStyle', 'docked')
set(0, 'DefaultFigureColormap', jet), close all

With the line of code commented out: set(0, 'DefaultFigureWindowStyle', 'docked')

The errors were resolved.

I posted this question (with a workaround answer) here because I saw no help related to this issue. Hopefully MATLAB team could find a better error message or an automated "undocking" event so a first time user of Database toolbox can have a better initial user experience. But at least this post can now serve to help unravel this mystery for new users as well.
