Error with Lua plugin on Windows

Hello,

I have noticed some errors with the Lua plugin on Windows. I am running 
0.99.0 on Windows XP SP.
I am new to Lua so I apologyze  in advance if I don't use the rigth terms.

1)  Compilation error with the Trivial protocol in 
http://wiki.ethereal.com/Lua/Dissectors.
The protocol declaration refers to the Protocol class (or is named a 
table ?) seems to be wrong . The following error message is displayed in 
a pop up:
 Lua: Error during loading:  [string "trivial.lua"]:4: attempt to call 
global 'Protocol' (a nil value)
The error seems to be fixed by changing "Protocol" into "Proto"
I can change the Wiki page the but I would like to have a confirmation 
before.

2) I have a "run-time" error with this trivial protocol : attempt to 
call method 'add_item' (a nil value).
I tried to debug with print method, the tree, buffer varaibles looks 
fine. I really don't known what to do now, but I owuld be happy to help.

3) Some wiki pages point to the following URL that apparantly does not 
exist : http://wiki.ethereal.com/Lua/Proto

Best Regards,
Jeremy JOUGLET
