# To subscribers of the xforms list from "T.C. Zhao" <tc_zhao@yahoo.com> :
Thanks for sending the test program. Yes, the timer
seems to interfere with the operation of timers
inside fselect(). It turned out there was some inconsistencies
in fl_add_timer() in that it adds an activated timer
with no time associated with it. I've fixed the timer
in the current source and the test program seems to work ok.
You can also verify this by setting the timer
using fl_set_timer(fdui->fl_timer, 10000)
which "fixes" the inconsistent state of the
default timer. (you may also need to change
fl_do_forms() to while (fl_do_forms()) ;
to ignore the timer expiration.
