Plugin deleted, dialog box when closing Mulab

[yul]

Hello!! I have an obscure plugin that, even after being deleted from a rack, prompts a dialog "save preset" when closing Mulab project.

Is this normal? Isn't a plugin supposed to be completely cleared from memory after I delete it?

Thanks!!

Hello, first post in this forum.
First at all, I congratulate to developer to make this piece of art of software, i no regrets from buy it. is all deserved.

Now to the topic.
I noticed that, when i update some plugins that i made in synthedit, it sems to be preloaded even when the plugin is deleted from Mux/mulab, because it keeps the .dll locked until i close the software.

A plug that is removed still is available for undo. If you clear the undo-redo history it will de deleted.
