flags in getCursorLoc

[Vincenzo Della Mea]

Dear all,
I'm trying to use the getCursorLoc(x,y,z,flags) function to individuate  
some location in the image, differentiating between left click and  
leftclick+shift; however, something strange occurs, as when I left  
click, I obtain a flag=16, while if I just press shift without  
clicking, I obtain 17. Furtermore, after 17 remains still in the pipe  
even if I release the shift key.
Any idea?

Thanks,
Vincenzo

ImageJ 1.35q, due in a few weeks, fixes a bug in the getCursorLoc()
macro function that caused it to not update the flags when the mouse
button was pressed or released without the mouse having been moved. A
more reliable way to check the state of the modifier keys is to use
isKeyDown("shift") and isKeyDown("alt").
