I want to change the value of the parameter [CTEDIT]MaxHelpRec in the citect.ini file but each time I change it the default or previous value is still used.

If the value of the parameter [CTEDIT]MaxHelpRec is changed in the citect.ini file while the Project Editor is running then the parameter will still be set to its previous or default value after the citect.ini file is saved and closed. The reason for changing this parameter's value is usually because you have got a "list too big" warning when opening a listbox in the Project Editor or Graphics Builder - see Knowledge Base article Q3605.

To successfully change this parameter you must close the Project Editor before editing the Citect.ini file. Alternatively, rather than editing the parameter directly, just change the 'maximum list box items' setting through the Project Editor's Tools|Options dialog box.

Citect has confirmed this to be a problem in CitectHMI/SCADA version 5.XX to 6.00. We are researching this problem and will post new information here as it becomes available.
