Naw. It recognized the mouse event; Motif, due to the register pop-order bug,
just didn't get the correct result from an X toolkit routine. Adding a line
like ptr++; ptr--; forces the problem to go away (as does any lvalue reference
in the routine; the pop-order bug only occurs in routines where a register
is used as an lvalue of itself).
Using Motif 1.2's patched Xt routines fixed it.
I've had /dev/tty00 and /dev/tty01 instead of /dev/com1 and /dev/com2 since
about day 1, so I never had the select() problem personally, mostly because
I serendipitously fixed the select() in the com driver at the same time I
made it conform to my idea of "pretty".
