"VirtualFileStream" demo Source to browsers triggering "OnGetStream" many times

[gsantoscosta]

Using the "VirtuaFileStream" demo as source to windows explorer, it working fine. The event "OnGetStream" is triggered just once, when we drop releasing the mouse button.
But, using the same demo as source to some browser, as Google Chrome or Edge, the event "OnGetStream" is called many times while mouse move on them, even without the drop.

My app was creating the file in this event, I'm trying to move it to some other way,
even though, the "get" will happen many times, and the process done would depend on the page open on the browser.

There is some way to trigger the "OnGetStream" just once, as the explorer?
