The program *itself* is 149 megabytes? Or the program plus its databases? My guess is this problem has to do with the DBCache on the T5. All previous Palm models store everything in battery backed RAM, but the T5 stores it all in flash and temporarily copies it to RAM (the DBCache) to speed up performance. The thing is, in order for the data to be really saved, it needs to be copied out of the DBCache back to flash. If the program is modifying lots of records in a database, it could take lots of time to write those back from DBCache to flash when you close the database(s) (i.e. when the program exits). You might try putting a DmSyncDatabase() call in at any point after you've just finished changing lots of data. This should flush right at that point, so that lots and lots of changes don't build up and take forever to sync when sync finally happens at app exit. If the program itself is actually 149 MB, then I suppose it may have to do with how the T5 supposedly reads in an entire resource database when it's opened (and presumably has to rewrite it to flash when it closes), but on the other hand, I doubt that's it since according to how I read it, it would be impossible to open a 149 MB PRC on the T5. - Logan -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
