Browser related issues and workarounds
This section contains a few glitches with browsers and some workarounds in order to get the maximum out of your MyWebSQL experience.
The opera browser has a default security mechanism which makes web applications NOT be able to receive right click and context menus events. Since MyWebSQL utilizes the context menu functionality, the menus may not appear at all when using certain versions of Opera browser, while in some versions, you might see two menus: Opera’s own context menu and the MyWebSQL context menu.
Please refer to your version of Opera browser’s settings dialog and find the option which allows webpages to receive right click events. If successful, you should be able to use the context menus just like other browsers.
