Trouble in using some of SimGallery features

I like SimGallery very much, but I have trouble in using some of it´s features.
I can not delete a single picture. It works fine to delete whole albums, but not with a single picture.
Also I cannot move a picture to another album. There is a popup flashing up, but only for a very short moment.
Can you please help?
