XYplorer Beta Club

Every time I start XYplorer x64 i get this annoying popup, telling me that there is no floppy disk in drive 4.
Drive 4 is my universal card reader with 4 slots. Although I only have 1 slot activated, I have to respond to the popup 4 times before it disappears.
If I untick "Show hidden drives" the card reader disappears but I still get the popup.
The latest XYplorer x86 do not give me any popup's.
XYplorer x64 v28.10.05

And that does happen in a fresh instance as well?

This message does not come from XYplorer.

I just tried fresh downloaded programs with default configuration:
x64 = popup
x86 = No popup

When does it pop up? Before the main window?

Yes, initially there is only the popup.
When I then respond first time (buttons or X), I get a blank XYplorer behind the popup.
After the 4 respond, XYplorer behaves normal, unless I click the card reader, then it starts all over but this time with XYplorer in the background.
I can add that this does not happen with any other filemanager I have tried.

What are the drive letters?

The card reader is X:

Could you show a screenshot of This PC in Details view, like this:

I get no popup if I insert a card...

I meant in XYplorer. I need all the columns shown in my screenshot.

Filesystem is blank

Do you also get the popup when you run this script: exist "J:\"; ?

Filesystem is blank ... oh, that's a bug!

I assume you mean X:
Yes I get the popup

Yes, I meant X. You get the popup one time?
