Dear Plucker developers,
I try Plucker 1.1 and like it. Thanks for your work.
Yet a bug occurs to me when it opens a large image (I tried the book "Thinking in
Java" using 8-bit bpp). The handheld simply crashes and needs reset. This problem is
repeatable in the POSE simulator.
Though new to Palm programming, I read the code and do some experiments (as a learning
process!), and figure out that the function UnZip in file uncompress.c is causing the
problem. The following quick fix seems to work. I'm not sure whether UnDoc (or
elsewhere) needs similar changes or not.
Hope it helps. :)
