• The log window now opens in the bottom-right corner of the screen.
• Renamed the measurement results window to results window.
• Resolved conflicts in the handling of mouse wheel events in the image window.
• The results window is now put to front every time results are written to it.
• Related windows are now put to front when pressing the F key in the active image window.
• The main dialog is now initially put directly next to the image window.
• Added a program option to let the main dialog move along with the image window.
• Movie maker now shows the true slice and channel per point for a single track in 5D.
• Leading/trailing frames are now omitted by movie maker when the Ctrl key is down.

1.0.1, October 12, 2006

• Zooming in/out can be done using the +/- keys at any time (if the image window is active).
• Temporarily switching to scrolling mode during tracking can be done by pressing the space bar.
• The program should now also work with the Java 1.4 runtime environment.

1.0.0, October 2, 2006

• The minimum requirements for this release are ImageJ 1.37r and Java 1.5.0. The program was tested and found to run properly on Windows XP (Service Pack 2), Linux 2.6.18 (Ubuntu 6.06), and Mac OS X 10.4.7. I haven't had the possibility yet to test it on other platforms so I don't guarantee anything there.
