# To subscribers of the xforms list from Jeff Pierce <wd4nmq@comcast.net> :
Enrico,
Thanks for the information. Removing teh XInitThreads() fixed the problem.
So, now what is the purpose of XInitThreads(). According to the man
pages it seems to only be needed to lock out a context from the main
event handler so a thread can make x calls to it with out interance from
the main thread event handler.
Is that a correct assumption?
