Saw this thread on the Vista forum and it describes exactly my problem, but I have XP so the suggested fixes aren't applicable. Just received my first T60p after benefiting greatly from this forum. Happily, I haven't run into significant problems and I've been able to fix the minor ones EXCEPT for opening pdf files from the internet or a memory stick. I've installed Adobe reader 8.0 but I get the same error message above when I try to open a pdf. When I say ok to the installer, it tries to install Reader 7.0 until it realizes that 8.0 is already installed and freezes. I CAN open Reader 8.0 and then open the file but this is a time-consuming workaround.Quote:akurza2 wrote:When I try to open a PDF online it asks me to install Adobe. When I install it, I get an error box from "Netopysytems Size Optimizer 1.0" that says "Another instance of this program is already running. You cannot run multiple instances at the same time."
Any suggestions?
Thanks much.
