I've altered nothing within the program, just uploaded a folder of images numbered sequentially to the server, pointed the program to the folder and let it do what it has to do.
But instead of the images displaying in order 0001, 0002, 0003 etc they display randomly.
I use I.E. as a browser; I don't mind using something else if it solves the problem.
When I said it jumps to the top of the page, I may be able to explain better.
Of the larger size thumbnails, each row contains 7 images, so with 260 images I have about 37 rows.
If I want to put an image from say row 20 into row 36 as soon as I pick the image up it jumps to row 1 and then I have to drag it all the way down to where I want to place it.
Very tedious and boring and prone to errors being as I need to hold the mouse button down and scroll the central wheel at the same time. But I'll load Firefox or something and try a different browser if I.E. is considered to be the problem.
