Hi Marcel

This happens because the row height does not automatically scale according to the text height. This depends on the font and its size, on Windows XP it looks well, on Windows Vista not. 

You can increase the rowheight manually which solves the problem. Just add following code into the plugin.xml of your swt plugin:

   <extension
         point="org.eclipse.scout.rt.ui.swt.lookAndFeel">
      <properties scope="global">
         <property name="formfield.activationButton.height" value="24"/>
         <property name="formfield.activationButton.width" value="24"/>
         <property name="logicalGridLayout.rowHeight" value="24"/>
         <property name="processButton.height" value="24"/>
      </properties>
   </extension>

This increases the height of the row by 3 pixel.

Regards
Claudio

workaround implemented for Juno: when OS != WinXP the default height is set to 23.

This is sufficient as long as the text scaling of Win7 is not increased above 100%. Unfortunately on some screen resolutions win7 sets a default text scaling of 125%. in this cases the text is still jumping. for affected users the solution explained in Comment 6 can be used.

In the future a dynamic layout would be desirable which always uses the correct height.

removed obsolete bugs due to new HTML UI.
