ms busy summer

I have been playing a bit more with beta2 , and I think Microsoft programmers are going to have a busy summer.
Beside the performance problems and other quirks, just browsing folder seem to be broken ?
I'm in "windows photo gallery" and I'm browsing the images that I captured, I right click on a picture and I "Open file location" ... the browse window only show me 4 files out of 50+, the one I right clicked on is not there. Right click on the file in "windows photo gallery", and confirm its location and access : Same location, no hidden flags, etc... Use copy pasting the file property path and dir doesn't show its existence. I use the search feature and those file don't show up Only "windows photo gallery" can see the files and open them... even while viewing the picture doing a "Open"->"Paint" tell me that Paint cant find the file
I go to use "Windows Mail" to post this report, and when I use the newsgroup list the scroll bar expand to gigantic distorted box when I click on them... all the rest of the system is OK but those two scroll bars.
Then I try to document the problems with print screen and Paint give me a clip board error on the first ctrl-v try.
I only casually use this beta, so this give me the feel that if its that easy to find this problems, the actual code base is in big trouble for a RC anytime soon ?

PS: When I go to speel check this, the speel check keep moving location (and fading in / out) each time I 'ignore' or 'change', thats a bit annoying.
