Found this issue a while ago
If you search a file in the 'Search' Data Pannel, you can open the file. However, we have found this opens the file extremely laggy and borderline unusable - we have found you need to search for the file, open its location and then open the file - this allows the file open in a workable state
I found this issue a while back and another one of our Engineers was complaining to me about it today - until I told him this work around
Does this issue happen with others - can others try to replicate this problem? Every local system I've tried this on has this same problem - wondering if it's a Bugg?
