Ken, Thanks for the clarification. I thought that the XPREF resource was needed to make the application "overlay-able".

No size limits beyond your available memory and the existing 64K limit for each resource chunk. And Kevin wrote: >Your application's resources must also have an overlay preference.

What you're referring to here (the xpref resource) is used to disable overlays. And finally: >I got it working and posted my finding in another post.

Although I suppose this could prevent someone from creating >an overlay from your base .prc. and using it. Right. Some companies sell localized versions of their products (often for more money than the English version), and thus are not excited about the OS making it too easy for a random 3rd party to distribute localization overlays as a way of gray-marketing their products. -- Ken Ken Krugler TransPac Software, Inc. <http://www.transpac.com> +1 530-470-9200 -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
