[RC14] Slow file opening time

I opened several projects just now to remember what some of them were. The “Open File” window itself seemed to be the issue. The first two-three files opened fine, but after that it lagged. I thought perhaps it didn’t like that I had inadvertently opened 4 projects at once but closing the extra projects didn’t have an effect. And most of these projects were small and the open destination was a local drive.
