Yes, it’s been noticed, but I don’t know if the author is aware of it yet.

I’ve started testing with a copy of my setup… with all other plugins deactivated, multiple instances of the PHP Code Widget work as expected, both with the default theme and Thesis 1.5.1.
When I reactivate all plugins, the problem recurs. So this seems to be a plugin conflict rather than a problem with PHP Code Widget itself.
Ignore my previous comment… previous instances _do_ disappear even with no other plugins activated with the default theme when a new instance is saved.
However, since the plugin is a basically a one-line change to the default text widget, it shouldn’t be too hard to create a version to work with 2.8.
Andrew Ozz sent me a fix for it today, which I’ve put in. I didn’t want to go the full widget class route with it yet in order to maintain backwards compatibility, for now.
Eventually I’ll change it to be 2.8-up only.
@otto42 Thanks, the fix works for me.
so version 1.2 is the one that works now with 2.8 and multiple instances?
Indeed, I’d like to know if the latest downloaded plugin has been updated with this fix. Thanks!
I am running WP 2.8.4 with a variety of sidebars and a number of instances of PHP Code Widget 1.2. I deleted one instance of the widget and ended up with all instances being deleted at the same time.
