Bizarre behaviour of folder

[Terry Pinnell]

I've opened a folder X (a subfolder of my large Photos folder). There are
several other folders open. But X behaves as if it doesn't exist. I can't
operate on it or its contents in any way. And the mouse cursor vanishes
when moved over it.

I used Task Mgr to close explore.exe, then re-started it, expecting that
to fix it. But the strange behaviour on this folder persists.

I'll reboot my PC next (can't do so until I finish rendering a large
video) but meanwhile wonder if anyone has any ideas about the possible
cause please?

Possibly hidden? Folder oprtions, view tab , check settings (show hidden
filkes and folders, etc.)

Did the reboot help, or no?
Have you checked for malware, offline.... that is, booting with an
anti-virus bootable rescue disk such as the Kaspersky rescue CD?
Have you at least done a full malware scan from within Windows
(anti-virus, anti-malware) plus a root kit scan with TDSSKiller?
