Don't know why attachment still doesn't show up. Anyway, the following line is shown by win7 (Computer->Properties): Installed Memory (RAM): 4.00GB (3.25GB usable). Task Manager->Performance shows 3326MB as Total Physical memory. This is 64 bit win 7 for sure. Why only 3.25GB shown as usable? Under Vista 32 bit, it was the same. Only 3.2 GB was shown as usable. I thought upgrading to 64 bit (it was a clean install during "upgrading" of course) will help.
