Bizarre Problems with Leopard+PowerPC

[Kevin]

Hi All,

I have had two users report issues running my Revolution-created  
software on Leopard. There are two things that have been reported:

1.  When the application is launched, the OS returns an error message  
stating that the software is "not supported on this architecture"
2.  The application opens correctly but freezes when attempting to  
use Revolution's XML external

I find the whole thing extremely bizarre since 99.9% of users  
(including myself) have had no issues running the software on  
Leopard. The one similarity I have found in common between the two  
incidents is that both machines are PowerPC Macs that have been  
upgraded to Leopard. I have built the software as a Universal Binary  
and experience no issues while running on a PowerPC Mac with Tiger.

The problem must almost certainly be on the Revolution side which  
makes it all more worrying because it seems out of my control. Any  
help would be much appreciated. Alternatively, if anyone is running  
Leopard on a PowerPC Mac and can volunteer to try it out, I would be  
very grateful if you could contact me off-list: candywriter <at> mac.com

Many thanks,

Kevin
