Windows 7 - 'open containing folder' command doesnt work

Hi!

Would really appreciate it if anyone could help me on this one!

I've noticed this problem when using a couple of different programs: firefox and UTorrent.

It happens in firefox when I open the downloads window (CTRL + J), then right click on a download - bringing up the 'open containing folder' option. If i click on that, it thinks about it, then nothing happens.

I've also noticed the same problem with UTorrent - when you right click on a selected Torrent and select the 'open containing folder' option -the same issue occurs.

Very sporadically this command does work (firefox only), but only about 1% of the time!

I have the most recent versions of firefox and uTorrent installed. I'm assuming this is a compatability issue with Windows 7 - as the same programs work fine with my other computer using XP. I had the same problem on my work computer using Vista. The computer I'm currently using is Windows 7 64 bit.

Any help would be really appreciated as this command is a huge time saver with my workflow!
