Stuck at processing

Tried to use it tonight on my BQ M10 running UT OTA 16. I was able to import a small png image and crop it, but it stuck at processing. I also tried with a jpg image and the same thing happened. This was a pity as it would have been ideal for generating a custom icon for use with webber. Now I will have to move to gimp on my laptop instead of being able to do everything on my tablet. Hope it turns out to be a simple fix.
