This kicked off an avalanche of forum posts spanning nearly a month that has gained some acknowledgment from Adobe about the problem, but no fix yet in sight.

Meanwhile, similar posts cropped up on the Apple forums as well. For users who can roll back to OS X 7.4.3, the problem could be solved, at least for now. But those that bought their brand new systems with 10.7.4 already installed do not have that option.

Adobe technician Scott Worthington first replied to forum users on June 27, saying that Adobe is looking into the issue, but offered no further comments until July 6, when he told users, "At this time it appears the update is removing an API we use to control our use of system icons," Worthington wrote. "At present the solution appears to be to rollback the update for the software to continue to function as expected."

While there are always some glitches with new software versions, and how they work with the current or future operating systems, Adobe's own page does not list this problem at this writing.
