Capture One Pro - Sony 14.1 - Much Improved

I'm on a Windows Intel I9 8Core PC, nVidia RTX Display card, 16G Memory. 

Capture One Pro 14.1 is pure magic now.  Import is instant, no matter how many photos I have to import at once. I haven't figured out preview. But I normally preview/cull all photos from my hard drive in Irfanview.  

The lock up on sliders is just a second or two now.. not 15 seconds. 

I was just using the crop tool. Readjusting the crop. The crop tool on the preview disappeared and when I clicked on the Crop Tab crop tool icon the photo preview disappeared and the preview screen was completely gray. Like it deleted my photo. I closed COP and reopened it, after waiting a while. That didn't help. The crop button at the Crop TAB was still orange. Photo preview was still blank. I played around with clicking on the crop tool tab crop button and at the Tool Bar. The photo finally came back in the preview screen but the crop marks didn't show. Clicked around some more and they finally came back too. Absolutely weird. Working as normal now.  All this took about 15 minutes out of my schedule for editing.. causing much anxiety. 

90% improvement for me.
