SYMPTOMS

A Visual Basic project uses the Toolbar from the Microsoft Common Controls 6.0 ActiveX control (mscomctl.ocx). At run-time, you double-click the toolbar to display the Customize Toolbar dialog box. When you add a Separator to the Toolbar buttons list box, the size of the existing toolbar buttons changes in the toolbar control.

From the Project menu, select Components and add a reference to the Microsoft Windows Common Controls 6.0.
Add a Toolbar to Form1.
Alternate-click on the Toolbar and select Properties. From the Buttons tab, add two buttons to the Toolbar.
On the Run menu, select Start, or press the F5 key to start the program.
Double-click the toolbar. The Customize Toolbar dialog box appears. Position the Customize Toolbar dialog box so that you can see the Toolbar buttons in Form1.
In the Available buttons list box, select Separator and click the Add button.

BUG: When the Separator is added, the buttons on the Toolbar grow larger.
