Hi folks,
yet another update on this, I sent a copy of the Smartcrash O/P to IB support mailing list and had some feedback from Oliver and Phillipe :-
"the 68030 (41Mhz) FPU is a 68882 (9mhz)
I think there must be some issue with your 68882 then - do you have any FPU
enabled software? It's either a hardware problem or something on the
software side not detecting the FPU or making it available to the OS and
apps. I'm afraid I can't remember back to my Blizzard 1230-IV days when I had
an FPU - not sure if special libs, etc, had to be installed as with 040/060
cards whose built-in FPU does not handle all the 68881/2 instructions.
FYI, I traced the smartcrash output to an FMOVE.X instruction which is causing
the crash on your system, but I don't see any problem - there is no reason
for it to crash on a 68882 as it's a common and legal instruction.

Maybe wrong or mising math library installed

So I checked my math libraries which were 37.1 /38.1, I found an update for mathtran.library on Aminet to 43.6 and replaced the original. I then switched javascripts back on in IB24 and so far (8 days) so good i.e. I have had two hang
ups in that time, both of which I have been able to skip over with Smartcrash .... watch this space
