Update issued correcting an ordering problem in the DSM-IV algorithms. Report functionality has been disabled for the time being due to compiler incompatibilities.

Further corrections made to the ICD10 and RDC algorithms fixing a problem with some depression and somatic diagnoses. The Farmer sub-type algorithm was also revised.

Corrections made to the ICD10, DSM-3R, DSM-4 & RDC algorithms and rating scales which fix problems with bipolar diagnoses (our thanks to Arvind Nongpiur for identifying the problem).

Corrected a problem with the language conversion causing elements to dissappear for Q49/51/52/53.

Language options added. Users can now create their own language files for Opcrit allowing non-english questions etc. Faults found in the SAS and Stata export routines were also corrected.

Ability to import CSV formatted data added. CSV file must contain the ID followed by the 90 ratings. One record to a line.

A printable report containing the summary field has been added, this can be used to print the summary for an individual record, or the entire dataset. The export routine for SPSS has been corrected and mousewheel scrolling support has been added for the dataentry and diagnosis panels. Finally, problems with the old Opcrit version import have also been corrected.

Item guidelines PDF added to the program adding to the overall documentation of OPCRIT. Also added a further export option for generating ASCII csv files from OPCRIT.

Problems found in the DSM-IV & ICD-10 Algorithms related to question 52 corrected (our thanks to Lisa Jones for pointing out the problem).

A couple of small errors were found in the algorithms for DSM-IIIR and DSM-IV. These have been corrected. The scroll bars have also been altered so proper scroll dragging works. Use the "WinOp.exe" link to download the update. It is a replacement for the actual Opcrit executable. Simply save the exe file over the existing one (which by default is in C:\Program Files\Opcrit for Windows).
