» Open this ONE file (the XPLnCODEd crasher), or a copy of it, and
make sure it still crashes KERNEL32.  Then start removing characters (or 
the opposite «

After considerable slicing and dicing, loosing my place, and fearing to 
add further user error, I tried this: I created a short file by copying 
the 3-byte codes from the top of Xywwweb.reg, added some identifying 
delimiters (so I'd know what I was doing), EnCoded it, and tried 
Clipping that. Illegal operation resulted. I then removed various lines, 
reencoded, and tried to Clip (see below). My VERY tentative hypothesis 
is that when you have 3-byte chars in the copy to be Clipped, there is a 
cutoff point between 385 bytes (max success) and 438 bytes (min failure).

» maybe this whole Tbird thing is a false positive and it really has to 
do with the specific characters that are being Copied/Pasted «

Yeah, you're right (as usual). At least, perhaps a combination of 
specific chars and size of block. (But my version of Tbird is buggy; 
will try and get the update next month, when I visit my brother, who has 
broadband. No DSL in the office.)

Will now try all this with 437 on the CommandLine. When I tried it in 
earlier stages, blocks that generated illegal operation  messages before 
were Clipped OK, so you're no doubt right about that too.
