I'm just starting out on rewriting a program into .NET 6 using VS2022. Some parts I want to keep the same, including some background images used on the main form. I was a bit surprised to see that resources are managed via the Resources.resx file, now, rather than in Project | Properties. That surprised me largely because you can still get there from Project | Properties, so I'm not sure why it was changed. Seems like more of an annoyance than a benefit, but that's not the point of this question.

To add a resource, I click on the Resources.resx file...which then does nothing for just long enough that I assume that nothing is ever going to happen, after which, if I haven't shut the thing down...up pops the same resource manager I'm familiar with. That makes it even more bizarre that they moved it out of Project | Properties, but whatever.

I then try to add a resource. In this case, I have a series of BMP and JPG images to add, so I try to add an image. At that point, a sub-menu comes up that shows different image file formats, including BMP and JPG. Can't DO anything with that sub-menu, though, because moving the mouse over the sub-menu even a little bit, causes the highlight to jitter back and forth from one menu item to the next in a spastic fashion. If I leave the mouse alone...well, then NONE of the menu items are ever highlighted.

Are other people seeing this? I ended up just adding a file, which contain images, but adding images just seems to be broken.
