Slow folder browsing: Local and Network

Hi All,

 I have recently installed Opus 11.  Folder display is slow on both local and network folders.  The problem is much worse with folders containing many files.  Windows explorer has no issues.  Any ideas on how to speed things up?

It's probably happening due to a bad shell extension.

Crash, exit or high CPU usage when viewing certain directories has advice.

You were correct! The culprit is Solidworks.
