VBandHack
Enables the full use of the BH8DZE CW trainer on the VBand website.

So when you press 'dah', instead of producing the sound you need (with the option mentioned above enabled), the browser just pops up a context menu. My program works in a very straightforward way. It intercepts mouse clicks when it detects that the VBand site is open, and replaces them with keyboard presses: 'LEFT CTRL' and 'RIGHT CTRL'. And everything OK! !! Disable 'Use mouse buttons' !! -
