Printing a lot of reports at once or if Citect is busy while printing reports may cause Citect to crash. 

This problem is due to an error in the allocation of spool buffers. The number of buffers allocated at startup has been increased from 4 to 32 to fix this problem. Also if the number of buffers increases above this limit you will get a hardware alarm on the device and Citect will not crash. The limit of the number of spool buffers can be changed by the parameter

Min: 4
Max: 128
Default: 32

CIT has confirmed this to be a problem in Citect for Windows versions to 5.00. This problem has been fixed in version 3.40/4.20 Service Pack J and 5.00 Service Pack E.
