I am just tinkering with a script here that uses a custom display conduit to show some on-screen info temporarily until it is escaped, at which time the conduit is disabled again. While messing around with this, of course, occasionally I inadvertently forgot to disable the conduit at the end of the script, or it errored out before it got to the disable line. The result is unsettling, as the display then remains on-screen - even if one starts a new document! The only way I found so far to get rid of the display is to close that instance of Rhino and re-open it.
So, I am simply throwing this out here for info - is there a list/table or some other access somewhere of running conduits where I can find the ‘stuck’ conduit and disable it after the fact? Admittedly I am playing at sorcerer’s apprentice here as I have really no idea what all this stuff does in the background, I am just basically copying and adapting code from various samples I have found.
Here is a script which will create a “stuck” conduit. If you want to try it, please note that you will need to close that instance of Rhino to get rid of it after, so use at your own risk. Normally, if you uncomment the last line, the conduit will be disabled if you hit Enter. As is posted, with the last line commented out, a dot will get “stuck” and not be able to be removed.
