Sometimes (but not allways, maybe 1 out of 5 times) I got the problem that when I want to choose the folder to open, the dialog is open and after some time it is interrupted with some other dialog for really small time (you can only see it blink). After that you need to click OK several times to make the dialog response (maybe only wait would be OK).

I captured this on the video (attached) but due to the poor quality you cannot actually see the dialog (the blink is around second 10). However, I managed to make a screenshot from higher-quality video I have on my computer.

It seems it is an OOmph dialog so I am not sure it really relates to the easy import component at all. But maybe you do work with Preferences and could avoid the OOmph invokation.
