[Tclplugin-core] NewStream Error with UIE 5.50, plugin 2.0 during a simple file ca ll

[<Pat...@in...>]

 <<Test2.html>>  <<Test.tcl>> 
Dear Source guru,
	i'm really stuck with this problem and don't understand 
why IE don't want to display the plugin runnning ?

When running Test2.html, the error is :
npNewStream
	in NewStream: invalid url "file://H:\Work\Test.tcl": non numeric port \Work\Test.tcl

Could you help me with this ??
Best Regards
