This has been a long standing problem in the GUI for adjusting something, I think gamma, but only in some types of images or intermittently. When it happened, I just typed in numbers to jump past 0.58. Perhaps I should have reported it. If I run into this again, I will report the precise scenario.

[You don't often get email from [email protected]. Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] [EXTERNAL] Hi Giovanni, yes I can reproduce it, also with a macro: Dialog.create("Try with right arrow to go past 0.58"); Dialog.addSlider("Slider", 0., 1., 0.55, 0.01); Dialog.show(); It looks like a Java bug to me; I could not find anything problematic in ImageJ. 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).
