Hi Michael, thank you very much for testing it and for the feedback. At least my doubts that the computer had a grudge against me are unfounded. Since there are ways to overcome the problem, I will just live with it. Giovanni

I tried two Java versions under Linux: Java 1.8.0_345-b01 OpenJDK 64-Bit Server VM java.vm.version: 25.345-b01 Zulu 8.64.0.19-CA-linux64 With this Java 8 version, when pressing the right arrow, it always hangs at 0.57 and never steps up further. Java 11.0.24 OpenJDK 64-Bit Server VM java.vm.version: 11.0.24+8-post-Ubuntu-1ubuntu320.04 With this Java 11 version, one needs two clicks on the right arrow to move from 0.57 to 0.58 and again two clicks from 0.58 to 0.59. On the way back, it omits the 0.57 and jumps directly from 0.58 to 0.56. I tried a few things like changing the "visible amount" (the width of the bubble that one can drag) to 0 or adding IJ.wait(100) delays; it does not fix the problem. The adjustmentValueChanged callback is performed correctly, and the AdjustmentEvent's getAdjustmentType() is also correct, UNIT_INCREMENT =1 or UNIT_DECREMENT=2, but getValue() gets stuck (here at integer value 57).
