Here I am with a shed-load of 6-8 year old blobs working with standalones of mine on ancient PCs running Xubuntu 18.04
(last Xubuntu version available for 32-bit processors) and, because they are of the post "I want it now" generation
they click and click and click on the start icon of a standalone so as many as 12 instances launch.

Is there some sort of code that can be written inwith the original stack so only one instance of a standalone will launch?
