Unfortunately, this is a bug in Java that we can’t control. In Windows 7 and 8, if you are using a font scale over 140%, some of the Bridge Designer’s dialog boxes become unusable. To fix the problem, you’ll need to reduce the font scale. Go to the Windows Control Panel and select “Appearance and Personalization;” then under “Display,” choose “Make text and other items larger or smaller.” On the “Change the size of all items” screen, choose either 100% or 125%, and then click the Apply button. If you see a slider, rather than a list of scaling options, move the slider all the way to the left. (Note: To access the Control Panel in Windows 8, type “Control Panel” in the Windows Search box.)
Some versions of Windows also offer a “Set custom text size” option. Be sure that this setting is at 125% or smaller.
