Thanks for the confirmation. I'll change the way I use this functionality (although the performance really suffers with large numbers of files - filter first is significantly quicker).
I haven't tried it, but I'm pretty sure that as a temporary bypass you could define a button to combine FlatView and Refresh into a single click operation.
I tried that first but received even more bizarre results. For some reason, the operations must be done using separate buttons.
What I would really like is to have a entry box for a filter view filter. Just enter the filter criteria and a flat view would be shown displaying just the requested files. But, I believe you cannot create or customize the entry boxes (such as file filter).
I tried combining these buttons again, but I do not get consistent behavior. Usually, upon hitting custom button, I see the results for a split second (incorrect as folders are displayed) then. immediately, the results are completely cleared. I have to hit the button, sometimes up to 4 times, before the results are displayed correctly.
Confirmed. It looks like any folders which are hidden when you enter FlatView MixedNoFolders will become unhidden. In other words, the folders' visibility is toggled instead of being set to off.
