>Do you change the owner of the chunk to 0 before passing it? I >believe you have to do that in order for it to be passed successfully. > This can't be true; PalmPrint uses the same mechanism for external apps to pass in information to be printed, and at least in the ones that we write (i.e., external apps that use PalmPrint), we never bother to set the owner of the chunk to 0. This *might* be necessary on a SysUIAppSwitch but definitely not on a SysAppLaunch. Although we don't use MemPtrSize so my answer can't be considered 100% definitive.
