After months of work, we have finally tracked down what appears to be the root of the "focus bug" on Tiger- it seems to be the case that the DivX 5.2.1 video codec will reliably cause this bug to appear on previously-unaffected systems, and removing it seems to solve the problem. Specifically, removing the DivX 5.component file from the root-level Library:QuickTime folder (it can then be moved into another folder for safekeeping if so desired) and re-launching Poser allows saving, import and export to proceed normally. The DivX 5.2.1 codec is not fully Tiger-compatible by DivX's admission, and hopefully they will release a Tiger-compliant version soon, but until then, removing the codec while running Poser does seem to fix the problem. Our SR2 updater should also provide a solution that allows the component to remain in place. Regards, e frontier Technical Support
