Hi,
when I extract JMeter-Plugins 1.1.3 Extras set inside Apache JMeter 2.9 folder then Edit menu and Open file menu got disabled in JMeter GUI.
Although I can open files using the tool bar's 'Open file' button.
I tested with all other JMeter-Plugins sets and this occurs only with JMeter-Plugins 1.1.3 Extras set.
The problem doesn't occur when using JMeter-Plugins 1.1.2 Extras set.
