I'm having a related issue, so I hope you don't mind me hijacking the thread now that your question has been answered. When I press F12 to take a screenshot in Fallout 2, it says that the screenshot was taken but no file appears in my Fallout 2 directory.
Some information: -
1.) I am using Windows Vista Home Premium (64bit)
2.) I have had trouble using this folder before: To adjust the settings for the resolution patch I had to manually copy the f2_res.ini file out of the folder, otherwise I'd get an error saying that I can't edit the file or the file cannot be found
3.) I do have UAC enabled and would prefer not to turn it off: May be related to the above.
4.) I do have antivirus running (Avira Antivir PE Classic)
If anyone could help me, I'd appreciate it. Google seems useless for this issue. ):
Update: Well, never mind. I managed to solve it myself. (: Took some messing around but I found the specific user control rights for that folder and gave my user account full control of the folder plus the files and sub-folders within it, now I can take screen shots. (:
