Hi to davygrvy,

my fix isn't for a thread related (deadlock) type problem - it 
is a fix for a double free type problem which is presumably 
screwing up the heap and causing the C runtime to hang.

It *is* with a threaded build (THREADDEFINES = -
DTCL_THREADS=1) which I think I enabled because I was 
using  'after' and it didn't work unless threading was 
enabled - but I may be mis-remembering here!

Also, I ended up doing all this with the debug build and 
found the -GZ flag useful - in fact it pointed out the fact that 
there was a problem with the heap.

It is worth noting that I have only seen this on Win98 and 
that using 'pythonw.exe' did *not* prevent this from 
happening,

regards John.
