Bug report: I discovered a serious conflict for file types that are set by the user to be played by Quicktime. For Quicktime file types, if a non-Quicktime player is set with a higher priority in LDM than the Quicktime player, then both players will show up on top of each other in the browser. More seriously, Firefox will become unresponsive (but can still be terminated).
The source of this bug stems from 2 sources: LDM and Quicktime. LDM because it creates an object tag for the highest priority player, and Quicktime because it allows users to set mime types in the browser. This problem may occur for other media types also (Windows, Real, etc), but has only been verified for Quicktime. Changing the mime types in VB will NOT fix the problem.
Solution: Change the media players priority in LDM so that Quicktime has the highest priority for all Quicktime file types. In VB control panel on the left side, select Links and Downloads > Players > then give Quicktime a high priority like 20 so that it's higher than the Windows & Real players. Now only the Quicktime player should show and not freeze up Firefox
