If Citect has been running without fault and then after you have experienced a power-failure Citect hangs or GPs on startup you may have the following problem.

On startup Citect opens the SYSLOG.DAT file, if this file get corrupted, Citect may hang or cause a GP fault. The SYSLOG.DAT file is kept open at all times so this file can become corrupted when a power failure occurs. The SYSLOG.DAT file is stored in the Windows directory which is normally C:\WINDOWS.

Do a SCANDISK to see if this file is reported to be cross-linked or corrupted, and simply delete this file.
