49	Trap on change mode.	Gregg Young	Gregg Young	"ASM51 and EBNF modes both trap on switch. It does not appear to be anything in the .fte file as ASM works and I have made the ASM51 .fte look basically the same and it still traps. 
In Hilit_SIMPLE (h_simple `16)
EColorize *col = BF->Mode->fColorize;

It also has trapped at the beginning of Hilit_Plain (+21) and Hilit_FTE + 24. These are what was being switch from and is probably this line for both:
HILIT_VARS(BF->Mode->fColorize->Colors, Line);

I also noted that switching to the RESOURCE highlighting on the same Plain text file (.trp) simply fails.

This has probably always trap but never been tried before."	defect	closed	minor	Release_1.0	eFTE core	PreRelease_1.0	fixed
