Hi, I have just updated to JAlbum 19 and now drag and drop freezes mid-drag.
I am using latest version of windows 10 home edition.
I tried dragging a whole folder, it froze. Therefore I tried just one picture, it froze again.
Click and open on one picture works okay, but I want drag and drop.
Since I do not normally use drag & drop I'm probably not the best one to reply to your post, but I did some tests to see if I can help explain what's happening. I also have jAlbum 19 and the latest Win 10.
If you create a new album, or open an existing one, click on "Add" at the top, click on "From disk", open explorer, find/click/drag the desired folder name to the open album, it will freeze. I didn't try it but I suspect that even dragging a single picture from the folder after having used "Add" at the top will also freeze. Task manager is required to get out of jAlbum.
If you do not click on "Add" at the top, use explorer to find/click/drag the folder name to the open album it will place the folder as a sub-folder to the open album. You can click on the folder icon in the open album and it will show the pictures in the folder, but if you make the album it will not contain any pictures.
If you do not click on "Add"at the top, use explorer to find and open the desired folder, highlight all the pictures in the folder, then drag them into the album they will all go in, and making the album works just fine.
I don't know if this is different from how it worked in version 18 since I had never used drag & drop with 18.
I'm still a couple of weeks away from being back at my Windows machine, but in macOS 10.15, drag-and-drop exhibits similar misbehavior. It's particularly bad if you try to drag in some images to start a new project.
Whenever JAlbum freezes/hangs you should turn on the watchdog under preferences. Then run JAlbum again and after it has stopped working for over 20 seconds locate the thread-dump.txt file and attach it to your post.
