Kevin,

Thanks for keeping me up-to-date. I'm really curious how the plugin
influences the speed on your iPaq.

Well, at the moment I can't tell what's the problem since I haven't looked
at the new StrokeMorph in 
detail. It must be something platform related, since the new StrokeMorph
runs well on desktop machines. 
(BTW: Have you tried using your iPaq image with the new StrokeMorph on a
desktop machine? (Just to 
make sure that the problem is not related to the particular image you are
using on your iPaq)). It might be 
a timing problem, but it could also be related to the way events (especially
mouse events) are generated 
by the device (resp. the VM). While capturing a gesture, the HandMorph is
forwarding every mouse event 
to Genie and to code for doing this is a bit tricky and already little
anomalies can make it go wrong. 

Debugging this stuff is probably not so easy. The main problem in debugging
stuff related to mouse events 
is the fact that every user interaction changes the way the events are
generated. In such a case, 
Transcript ouput is sometimes the only thing you can do :(.

But don't spend too much time on it! I'll have a closer look at the
StrokeMorph implementation as soon as 
I can (probably tonight) and maybe I'll find something. Otherwise, I'll just
try an alternative 
implementation. (Having a faster graphical feedback is quite important for
Genie. If it's slow, it isn't able to 
capture enough points and this has negative impacts on the accuracy. So, I
won't give up!  ;)

Cheers,
Nathanael

PS: You never experienced this errorneous behavior using the original Genie
StrokeMorph haven't you?
