I cannot select multiple files

Well, hello, and sorry for my English
I have Windows Vista x64 installed. After few weeks after installation the
problem had came: in some folder I can select multiple files, in some - not.
It doesn't metter wich way to select I use: simply with mouse with left
button pressed or with shift-button or ctrl-button or with ctrl+a. Also in
Windows Explorer orginize menu "Select all" item disabled (grayed). First I
think it's depend from file types in folder, but it is not so.
Any ideas?

Not sure what to say, other than I've had it happen to me. I think I messed
around a bit with folder options and got it fixed.
