Problem: Right-clicking on a row in the Databases tab or in grids, the data is scrolled one row up or down before showing the menu, which means any selected action in the menu will be processed on wrong row. 

Reason: This is a regression introduced in Java 1.8.0_121 and was fixed in Java 1.8.0_152.

Solution: Download DbVisualizer 10.0.3 (or newer) with the JavaVM bundled. It includes Java 1.8.0_152.
