On my office machine, v1.09 of the plugin not only doesn't work, but prevents N++ from launching - an hourglass appears for 15 seconds or so, and the process dies without any error message. No php_error.log was genereted.
This happens regardless of using an administrator account on WinXP32 SP2.
v1.03 does work, though the script repository crashes - executing scripts as N++ documents is fine.
The problem has been here since v1.05.
