Hi Jon,
here a log of my recent tests. The most interesting point is the last.
1. I modified file C:\Program Files\Synaptics\SynTP\TP4table.dat according to new FAQ and reboot PC.
-> No change of behaviour.
2. Download XWin.20120129-git-45e67e363e19a481.exe.bz2.
/bin/startxwin -- /bin/XWin.20120129-git-45e67e363e19a481.exe -logverbose 3 -clipboard -emulate3buttons 100 -nounixkill -nowinkill
-xkboptions nbsp:level3
-> Doesn't start. Error message on the console is:
giving up.
/bin/startxwin: No such file or directory (errno 2): unable to connect to X server
/bin/startxwin: No such process (errno 3): Server error.
-> No output at all to file /var/log/xwin/XWin.0.log.
3. I took above startxwin command line and replace XWin.20120129-git-45e67e363e19a481.exe by XWin.20110803-git-a493c0465e56ce0b.exe
-> Immediately starts. All further tests with (old) XWin.20110803-git-a493c0465e56ce0b.exe.
4. Today I couldn't get to the broken, jumpy behaviour by scrolling a Windows dialog.
So this is not the breaking condition as I previously meant.
But after some time, the scrolling behaviour breaks and xterm scrolls in jumpy way.
Sorry, I have no glue what's the condition that breaks it.
After reboot of PC it scrolls fine. Any work of 1 minute or so seems to break smooth scrolling.
5. Then I started ico.
-> While ico runs, xterm scrolls fine and smooth. As soon as I stop ico, xterm scrolls jumpy.
-> Pressing the trackpoint button has no effect to ico. It keeps painting fine eather way.
Regards,
Paul
