Adobe Reader 6 can take a long time to load.
I am running windoze on an old box and it can be painful to wait so long to open a .pdf file.
A friend recently gave me this tip.
Navigate to the directory containing Reader 6- then find the "plug_ins" folder.
Rename this folder to something else; "plug_outs" for example.
Create a new folder called "plug_ins", then copy these three files from the "plug_outs" to the "plug_ins" folder.
This fix will greatly speed up the time it takes to load Reader!
