Hi there,
I've a strange error since some time, and have opened a Ticket https://www.virtualbox.org/ticket/18214, which seems to be the wrong way. So I should have posted my issue here first.

When if hover optical media menu, which contains an inaccessible or offline media, the vm crashes. Happens mostly after vm start.

I'm Using Windows 10 1809 x64 Pro, guest seems to be any, novell to windows. Problem exists since <= Vbox 5 and host os <= Windows 10 1609.

Start VM
Menu -> hover Optical media
an last used optical media exists which is on an inaccessible/office n etworkstorage
the vm freezes and crashes after some seconds
if you leave vboxmanager open, a second try works,
if you close it, its crashing again

Anybody else can reproduce this problem or help me with that?

Thanks for your help.

This is usually a fault in your host with some other driver, e.g. for Bluetooth. Think of anything that you installed (not native) which may attach itself to a file open dialogs.

Serpen,
How many VMs do you have?
How many CD entries do you have in the Virtual Media Manager > Optical disks?

Hi mpack, thanks for your answer. The crash is before opening any kind of file dialog. its when opening the menu.
And i've never seen this in any other file open dialog.

I think its an issue in the function which generates and checks the recent images.

Hi Socratis,
14 vms
22 optical disks in the manager
the menu shows one physical drive, and three recent images.

And sorry for asking, why not to quote? So I clicked Post Reply and the copy the quote from another tab.

I mananged to reproduce the problem on another system. Surface with Win 10 and Virtualbox 5.2.4.
The problem seems to only occure when there is a cdrom drive mounted in windows. Without the problem doesn't occure.
My PC GUI/RecentListCD is Networklocation,Networklocation,localnotfoundlocation,networklocation,networklocation
My Surface GUI/RecentListCD is net,net,local,net,local
The crash does not happen when modifying the cd rom settings of an offline vm, then the cd pop up menu only takes an minute or so, but still freezes the app.

That's something that the developers will most probably appreciate...

And sorry for asking, why not to quote?

Quoting in itself is not bad, on the contrary. If you quote specific sections, by all means do, it makes the discussion clearer. But the problem is that people mostly quote the whole previous message, verbatim; a two page quote for a "Me too" reply. It makes the whole thread quite unreadable.

You have the previous message right below the reply form. You select the passage you want to quote, and if you press the "Quote" in that message, it only quotes the specific selected text...
