Hello, Wayne Rasband, hello everybody of the ImageJ Interest Group,
I am using ImageJ to support my lecture and lab of Digital Image Processing i am teaching in my Bachelors' and Masters' courses. In the lab, the students (among other projects) are supposed to write a program to erode and dilate a binary image.
In part of this project, their program is supposed to erode, whenever the key with letter "a" is pressed, and to dilate whenever the letter "b" is pressed. Now some students have the problem, that the letter "b" is preset to some ImageJ function, so a window pops up that has nothing to do with their program. I believe that this concernes only users of Windows XP (including myself), but users with Windows Vista, do not seem to have the problem, some users with Windows 7 have the problem, others not, and Linux users (we had only one) do not seem to have it.
Question: How can we disactivate the pre-setting of the keys in ImageJ?
Any good idea is welcome
Thank you very much in advance!
Angelika Erhardt

In the new version, the "page up" and "page down" keys on my laptop (basically the up and down arrow keys) cause the image to zoom in or out. Is there a way to override this keyboard shortcut?

This opens all my tifs as a virtual stack, and allows me to use the left/right arrow keys to flip forward and backward through time in the stack, and the up/down arrow keys ("page up" and "page down") to move up and down through the z-slices of the stack. Right now, the up/down keys are simultaneously flipping up/down through the z-slices, and zooming the image in/out. I would like to override the zooming, so that I can just use the arrow keys to maneuver through the images of the stack. Thanks! --Monica.
