PSE v2024. Layer Mask contents not always showing up in the Layer Mask Thumbnail.
Shows up using Alt+Click on thumbnail but not in the Stack.
Anyone else experienced this or know how to resolve?
IF THAT DONT WORK: Open the editor preference file, choose "reset preferences on next launch", close, and restart the editor.
The screenshot below is from pse 2024--- earlier versions have the same option- the preference panel in those versions will look a bit different.
resetting your preferences fixes odd behavior, sometimes it just works, don't know why it works, it just does.
