Just had something odd happen on a win 7 machine where multiple copies of the
livecode app that runs on it (stripped machine that only runs this application
for a presentation system) some how got started up. I had bumped the app to
LC7.1 and over the last few months some random freezes were occurring (never
seen before in the system that has run for 20+ years of evolution from early
metacard!) and the multiple running copies of the same app was just discovered
happening with the current 7.1LC version.
Users were quitting out of the app when things would seem to stop working by
using an escape key handler i have that just quits the app (always has quit the
app in the past fine with no lingering copy). Its a live show so I never can
get detailed info on exactly the nature of the freeze up, but the escape key
handler works so its not totally locked up, some say the buttons dont function
others say it keeps working but external machine control does not work, others
say it starts working again after a 30 second pause. again its totally new and
random behavior, sometimes once a day sometimes not for two weeks. no
consistent screen or asset causing it it seems. The app is pretty simple in its
duties for revrun, basically little text db of video clips and thumbnails and
labels to be selected played by external video server with UTP commands.
But just finding multiple copies running makes me suspicious that they may have
been causing some trouble so trying to squash that first now! Also the nightly
restart on the windows box was not happening so windows was running for long
periods. Had that issue with one rev of windows that would get cranky after
running for a month or so straight w/o a restart.
Any ideas on how to prevent the multiple copies of the app from getting fired
up?
thanks
jeff
