I don't understand your question. I did a short test just now and it works as expected.
Double clicking a word selects it. Tripple clicking the editor selects all. Double click-hold move mouse selects words. Click move mouse selects area. If the selection is done, d&d works as expected, if 2 tiddlers are open in the same TW. It also works with 2 windows with open tiddlers in edit mode. I'm using FF latest and win 8.1 have fun! mario -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
