In that case, consider it a feature request instead

It can be quite annoying when you've got lots of tabs open, the tree view can become quite messy.

I'm aware of how the threading should work, my point is that it doesn't (or at least hasn't for me, on occasion). Often the UI thread is blocked by the calculation - nothing redraws and after a while windows reports that x2 is "not responding" - and the harddrive is whirring away (as it should) indicating that it's probably the folder size thing that's causing the blocking. When the calculation finishes everything returns to normal and the UI defreezes. I think this most often happens when the second-from-top tab starts the calculation and I use double-click on the tab in front to close it, but I'm not really sure.
The other (less common) half of this is that sometimes it seems not to calculate the sizes when the option is on (the hard drive is inactive, so it's easy to tell). I think this might be related to terminating the program when it's half way through the process (in the situation above), but again I'm not really able to reproduce, sorry.
This feature is only useful in some situations, so I've just turned it off for the time being anyway. I still thought I should let you know about this bug though.

looks like you have to install some codecs for the missing functionality
I can play these files fine and I have another file manager that shows previews fine. Perhaps you are only using VfW codecs and not directShow filters (or vice-versa)? Even MPEG1 doesn't show a thumbnail!
