I don't have this issue. But then, I'm running Windows 10 with new enough video card drivers.

I'm also running Windows 10 with all the latest and newest video card drivers. All the other drivers are the latest versions, on a desktop computer that had all the best hardware parts in December 2017. If this problem had something to do with a video card driver, I would have had the problem in 3.48, but I didn't. Version 3.48 was working very well, and I had no problems with the slowness in the File Preview window nor with the entire Editor window crashing, as it does periodically in 4.2.
My video card is a Nvidia GeForce GT 730 and the latest driver is installed, per Device Manager, at this moment.
Thanks for trying, though.
