#1:From a terminal:
~ joe$ mkdir a ~ joe$ mkdir b ~ joe$ cp .bashrc a/file1 ~ joe$ cp .bashrc b/file1 ~ joe$ vsdiff a b 2014-11-04 18:39:27.912 vs[28860:507] modalSession has been exited prematurely - check for a reentrant call to endModalSession: :~ joe$
When you run this you get two jumping SlickEdit icons in the dock.
One is a dialog claiming "File a/b does not exist".
This same command line and setup works as expected on Windows.
#2: "vsdiff -?" opens a *really* narrow window with the help text all wrapped and hard to read.
On Windows it opens wide enough to not wrap all the text.
#3: "vsdiff a/file1 b/file1"
This also opens two jumping icons on the dock.
1st is "files match, compare anyways?"
When I answer YES, I'm left with two Slick icons, one with a triangle overlaid.
The one with the triangle appears to be the actual side-by-side diff window.
The other one (that remains jumping for awhile), seems to not have a window associated.
Sure enough, when I do a "ps" from the cmd window:
28870 ttys001 0:03.38 vs
28887 ttys001 0:00.41 vsdiff a/file1 b/file1
28888 ttys001 0:01.85 /Applications/SlickEdit2014.app/Contents/MacOS/vs +new -q -st 0 -mdihide -r diff a/file1 b/file1
28870 is the "normal" vs that I have running, not related to the diff.
#4: When I click in the Diff window, then type Command-Q, I get "Command 'safe-exit' currently not allowed in Diff mode"
Note when the DIFF window first appears (given the above command from #3), even though the arrow keys will allow you to scroll up and down, the window does *not* appear to have focus.
At this point Command-Q does work - at least sometimes.
