Greetings,

I have noticed two specific bugs that have been present since the
introduction of the Intel Mac.  These bugs manifest on QuickTime
7.1.3 and 7.1.5.  These bugs are confined to Intel Macintosh only.
(Motorola Macintosh and Windows machines work fine.)

I have submitted a report to Apple starting in February of 2006.  So
far there has been no response in the bug report.  (Problem ID
4848000)  Here are the two bugs:

1. The "Show Hotspot" feature will not show hotspots in object movies.



Ted, I can confirm this problem as I had it happen to me recently. I was making an object movie with many, many hotspots. What was odd to me was that I could always see the hotspots in the authoring program of the object movie, be it VRWorx or Pano2QTVR (using Parallels) or when doing additional work on the object movie with deliVRator or Livestage Pro. These programs are certainly using QuickTime to display the object movie, but the hotspots that are visible in them aren't in QuickTime on my Intel Mac. At first I thought something was wrong with my movies, but collaborators said they were seeing the hotspots fine. It took a couple of rounds to figure out that it was only Intel Macs that were not showing the hotspots.

I wondered if the difference could be that QuickTime is a Universal Binary and the other apps are not and thus use QuickTime internally as a Rosetta application. Sure enough, if I click "open using Rosetta" on the QT Get Into window, hotspots in object movies DO show up normally!

So, evidently, the problem is in the Intel side of the QT code. You might want to mention that in the bug report.
