RE: Automatically positioned mouse movements are off target

["Brian Sheppard" <sheppardco at aol dot com>]

I addressed my problem using a different X server (xming). There was also a
commercial product that worked; I cannot remember which one.

For Xming, the key was to start it up in a specific windowing mode.
Something like full screen with no title bar.

I think that I tried all combinations of options on Cygwin-X and they all
failed, but maybe I did something wrong.

For me, the issue is resolved. But if you want to pursue it then Abbot
includes a test case that you can use to reproduce it. The Abbot installer
includes an app and a test script, and instructions
(http://abbot.sourceforge.net/doc/quick-start.shtml). You would install
Abbot on the Unix box and use X to view the execution of the test script.
When the script tries to click on a button, it will miss.

Thanks for the problem report.

I did some testing against Xserver 1.7.1 with xevent [1] and xdotool [2] to
position the mouse pointer, but I wasn't able to reproduce the behaviour you
are seeing.

I really have no idea how to get started using abbot to reproduce the
problem you see, a simple test case would help a lot here.
