First of all thank you for the program. I love it because it simplifies my life and looks my Win XP looks better.
I noticed one bug - I use two HDDs (divided into several partitions) and everything is correct with them. I also use a HP Flash Card Reader (internal USB reader, but NOT connected directly to the mobo ports. HP provides a separate controller connected to a PCI, with two additional USB connectors). The problem is that if no card is inserted Vista Drive Icon bars are always half full (or if you prefer - half empty). Should be blank bars. All the values are shown correctly when the card is inserted.
PS I use Windows XP Home Edition SP3 (slipstreamed) PL (Polish). Vista Drive Icon v.1.4.
