Win7 – latest download
I open a new file – background transparency
I fill all image with a colour, then I paint a simple O by hand in black
After that I go to Filter menu and I choose Morphological – Erosion (minimum)
then I need to UNDO – so in the menu Edit I choose and click on UNDO
So I click on that menu 3 or 4 times and nothing happens
but if I go away – the filter list desappears from my left too – , selecting a pencil, then the image is void, blank, as it was when opened as a new file…
The bug is the same when you use a filter of your choice, if you click on OK or cancel, you can do your undo simply and in a viewable mode. Otherwise your undo is working but in a hiding mode and you don’t know what happening. Maybe the better way is to use the UNDO and to render the exact image in that moment.
