In the System Restore window, it says: "System Restore does not affect any of your documents, pictures, or other personal data. Recently installed programs and drivers might be uninstalled. Is this process reversible?" I have had a problem since Vista of System Restore deleting some personal files from personal folders. It says above that it will not affect your "personal data" but it does. I had to do a System Restore yesterday (used the restore file before the most current) and when I tried to compile a program this morning, several files were missing. The folder/files were as follows: C:\CodeTyphon\Lazarus\ALazarusProjects\MyProjectTest\GnuPG empty keys fingerprint.txt gpg.conf gpg.exe - missing after doing a System Restore iconv.dll - missing after doing a System Restore pubkey.asc pubring.bak pubring.gpg random_seed secring.gpg trustdb.gpg C:\CodeTyphon\Lazarus\ALazarusProjects\MyProjectTest\Stunnel\ stunnel.exe - missing after doing a System Restore - others also missing after doing a System Restore (can't remember) C:\CodeTyphon\Lazarus\ALazarusProjects\MyProjectTest\Mixmaster\ mix.cfg - missing after doing a System Restore Wonder if this is a system bug? None of these files are pointed to in the registry. Thanks.
