Topguns locking up mame on exit

[brock.sampson]

I recently purchased two lcd topguns and have them all hooked up in my cab.  Since their installation I have been getting sporadic lockups when I exit games.  Below is what I'm running:

Windows XP
Mame 116
Smog Guncon2 driver .9b6
mamewah 1.62b13

mame.ini
mouse                          1
joystick                         0
lightgun                        1
dual_lightgun               1
offscreen_reload          1

Also tried mame.ini
mouse                         1
joystick                        0
lightgun                       0
dual_lightgun               0
offscreen_reload          0

I was originally running 113 but it was doing the same thing so I tried jumping to 116 to see if it would correct the problems didn't seem to help.  First noticed when playing xmen vs street fighter.  If I have the guns plugged in at least half the time when you exit it will lockup mame.  If I have the guns unplugged didn't have one lockup.  I also tried with and without mamewah.  Didn't make any difference if guns were plugged in it would sporadically lockup on exit.  I have only tried smog's driver I couldn't get the ems 3.2 drivers on the cd to work they always failed to load.  Anybody have any ideas on what to try next?

Jumping up to mame .118 fixed the lockup problems.

Yes. MAMEs from 112u? to 117 had a problem with the multithreading enabled and LCDTopGun plugged. Since 117u1, with the new Control  Input code, this bug has dissapeared and all work correctly.
