            Bug ID: 952
           Summary: Return value of IJ.showMessageWithCancel() is ignored
                    in macros
           Product: Fiji
           Version: unspecified
          Hardware: Macintosh
                OS: Mac OS
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ImageJ1
          Assignee: imagej-bugs at imagej.net
          Reporter: tiagoalvespedrosa at gmail.com

A (IJ1) macro calling showMessageWithCancel() is expected to terminate if the
user chooses "Cancel"
(http://imagej.nih.gov/ij/developer/macro/functions.html#showMessageWithCancel).

In Fiji, however, macros continue to run after pressing "Cancel". Example:

showMessageWithCancel("In IJ1 a macro exits when the user clicks 'Cancel'");
showMessage("But not in Fiji (unless it runs from the IJ1 editor)");

Running the above in the buil-in editor (e.g., Plugins>New>Text Window) works
as expected.

Probably not a major issue, but it will likely break some macros down the road.
