This is a funny behavior quirk that happens occasionally.
I use a lot of columns. If I've sorted files by a column on the far right and I'm looking at that column, and want to select multiple files, I click on one file, scroll down, hold down the shift button, and click on another file. Sometimes, this causes the view to shift all the way to the left. When the view shifts to the left, for a split second all the files disappear and I see I see a bunch of scrambled funny characters. It doesn't happen every time though. I think it might be related to how long I'm holding down the shift button after I left click, but I'm not sure.
Because I have so many columns, it takes a while to scroll back to the far right and that interrupts my workflow and that gets especially tiresome when I am working with many thousands of files, and need to focus on only a few at a time, and it keeps happening over and over.
Thanks for your time! I love this program.
