I have found one possible source of error and a solution to this problem:
I also just uninstalled and then reinstalled PlecoDict onto my Palm Treo 650. When I reinstalled, the dictionary worked, but said it couldn't find the handwriting recognition files. I re-installed them in RAM, still no luck. Since previously I had had the entire PlecoDict on my expansion card w/ no probs, I uninstalled and reinstalled all files onto my card. Still no luck, but this time, the dictionary opened in unlocked mode. Upon clicking on the PD Unlock file (also left over on my expansion card from before), the dictionary unlocked and the hwr worked!
So, don't know what this means, but for those of you having trouble getting hwr to work after re-installing plecodict, you might want to re-tap on PD Unlock to "re" unlock your dictionary and see if that helps.
Also, I have found that PlecoDict runs just fine when I install all the files on my expansion card (and none in RAM). The only downside to this is that the icon doesn't appear in the main menu, but only in the card menu. But the dictionary itself works fine. The user manual seems to indicate that this isn't possible. Don't know why.
