Drag & Drop problem - iTunes

[macuser940]

This is a problem that happened a year or so ago when I did a software update on my MBP that I'd like to ask if anyone can help.

I went from 10.6.5 to 10.6.7 (with the Mac OS X Update Combined which also updated to Java 10.6 Update 4, iWeb 3.0.3, Safari 5.0.5, Lexmark Printer Software 2.4 and Remote Desktop Client 3.4 all in the same session.)

Following this, I lost the ability to drag and drop iTunes tracks into Roxio Jam 6.0.3 (which I use and prefer over their latest version of Toast.) I can d&d tracks to the desktop or to other folders with no problem but when I drag a one over to Jam, the playlist window will illuminate but the track will no longer drop in.

Conversely, when I use the "Add"/"Choose An Object" feature in Jam, the "Media" area no longer populates with my iTunes library when highlighting "Music" as it did previously. Strangely, by using the same "Add/Choose" feature I can still access iTunes under "Places" or by drilling in through "Devices" but this presents the library as folders and track selection is tedious whereas "Music" allows very fast access to iTunes, complete with search window.

Does anyone know what could have happened as a result of this software update and is there a fix so I can get drag and drop back? I'm thinking that there's some file or preference that needs to be re-created.

Thanks!
