There appears to be a paste preset bug in HX Edit, at least with my HX Stomp running version 3.11.
The desired action is to paste the same preset multiple times, such as to clear out multiple slots with a blank preset or with a template.
Copy the preset. Select multiple slots. Right click and paste on one of the selected slots. HX Edit then prompts, "Are you sure you want to overwrite the highlighted presets?" Notice it says plural "presets." Upon clicking "Yes," only the first selected preset is overwritten, even if you right clicked on one of the other presets in the selection.
It gets worse. After pasting the first selected preset, if you then try to right click and paste on one of the remaining selected presets/slots, HX Edit jumps to the currently active preset slot, not the one you right clicked on. Not even one of the selected presets/slots.
I've lost a couple of presets this way. Tried to paste one preset into multiple selected presets/slots. Only the first one is pasted. Then, when right clicking on one of the remaining selected slots, HX Edit jumps to the currently loaded/active preset behind the prompt. The prompt asks if you want to overwrite the preset, and I knew what I clicked on, so I click "Yes," only to find out the preset wasn't pasted into the clicked slot, and instead overwrote the active preset.
Am I doing something wrong?
