Weird UI bug that is exactly what is reported at this link:
http://www.mail-archive.com/[email protected]/msg53307.html
The tokens in my NSTokenField disappear if I move the mouse into the non selected/currently editing field and then start moving the mouse out.
The tokens just flicker away.
it was because I had a core animation backing layer checked within the xib that contained my nstokenfields... very weird. Ill probably report to Apple on this buggy bug.
