I've been using dual screens at my office for some years now. After installing Windows 7 Pro x64 last fall, I was pleased to find that for the most part, program windows would open in the same place and same size and on the same monitor as they were on when I last closed them.
Some weeks ago, I started having issues with a PDF file opening in Acrobat 8 Standard on my right screen (where I want it), but then any subsequent PDF file opened while the first one was open would go to the left screen (NOT what I want).
Now, as of about 2 weeks ago, after installing a new nVIDIA Quadro FX 580 graphics card and replacing the left display with a Dell Ultrasharp 24" display, ALL PDF files open on my left screen. This is completely annoying because I do most of my work on my left display (the 24") and I need PDF documents to open on the right.
Someone posted a tip one time about moving a program window where you want it, maximize it, restore it, then maximize it again, and close it, and it should remember the location. This has worked for the most part, but not for Acrobat.
Any ideas? I am NOT running the nVIDIA nView software because it was causing graphics issues with some other software I use. I used to use it to force certain programs to open on certain displays, but for the most part Windows 7 keeps stuff where I want it without needing nView. Acrobat is the main one giving me trouble, and it seemed to start some time after installing the new graphics card and display a few weeks ago.
