Notepad++ hangs for the longest time over slow SMB connections. Version 4.7.5. Version 4.8.1 won't even load. I already turned File Status Auto Detection off. Trying to load a new file, or just switching windows, causes it to hang. I need lots of files open. The explorer also hangs when browsing SMB connections.

I have to revert to a previous version - very old version. 4.6.

After further experimentation, it was due to WindowManager plugin. That plugin should be taken out back and put down.
