Workarounds to some (appearance and locale) problems :
1. Cannot open recent files with unicode filenames: Create an environmental parameter with the name "JAVA_TOOL_OPTIONS" and set its value to: "-Dfile.encoding=UTF-8" 2. Awful icons in toolbar: In "JAVA_TOOL_OPTIONS" add "-Dsun.java2d.uiScale=1.0". Drawback: smaller characters in plot view. 3. For a more "Windows" look and feel add in "JAVA_TOOL_OPTIONS": "-Dswing.aatext=true -Dswing.plaf.metal.controlFont="Segoe UI Normal-15" -Dswing.plaf.metal.systemFont="Segoe UI Normal-13" -Dswing.plaf.metal.userFont="Segoe UI Normal-15" -Dawt.useSystemAAFontSettings=lcd" 4. Dealing with the small numbers problem in a calibration bar (i.e. numbers smaller than 0.1 are not interpreted correctly - see other post in this thread). Add in "JAVA_TOOL_OPTIONS" the value "-Djava.locale.providers=COMPAT,CLDR,SPI".
All solutions are working with the bundled Java verion (9.0.4) and newers.
First problem: Setting the length of the calibration stick, after the tracking of a mass point has been completed, the data table is not automatically updated. I have to press play button for the video to be reproduced and then the data table is updated. The same happens when I change the orientation of the axes from the toolbar.
Second problem: Defining a new fit function in data tool is not working. See attached picture.
When i enter very small numbers (e.g. 0.02 m) in the text field of a calibration bar, Tracker ( v. > 6 ) does not accept them, failing in the attempt to convert them into scientific format ( x.xxxe-y ). As a result the experimental data (position coordinates) that i get after tracking, are incorrect. The same happens entering the mass of a point mass.
I can't reproduce this problem on my Windows 11 machine. Can you give more details? Please use the troubleshooting guide at https://www.compadre.org/osp/items/detail.cfm?ID=16061 Doug

Hmm, that's a mystery. I notice you are using a period for the decimal separator. Isn't comma the default for greek? Did you set the decimal separator to a period? What happens when you use a comma?

I've already tried that, but to no avail. I actually assumed that changing from the default decimal point (comma) to period would solve the problem, but as i said that doesn't help. Tracker 5.1.5 works fine. Maybe is the 64bit Java engine that causes the problem...
The problem occurs with the bundled JRE (v.9.0.4). As i said problem solved using JRE 8. But it is very strange that with JRE 8 the model builder window does not open, unless the GUI font size is set to the smallest one!!!
