Is DateBk5 compatible with the new V-5.0 Palm OS?
Yes. You do need to be using at least V-5.1b (or later). DateBk5 runs on all versions of the Palm OS from 2.0 to 6.0 and will be updated for OS releases beyond that. The only known issue at this time is that DateBk5 does include a couple of menu shortcuts that require two strokes in graffiti 2 and some early OS/5 devices had a bug in the Palm OS whereby they don’t handle two-stroke menu shortcuts. This bug is fixed in all the very latest Palm OS devices. With the latest Tungsten/T5 and Treo-650, you must be using V-5.4a or later of DateBk5 due to some serious bugs in those devices which require the workarounds added into the V-5.4a release.
