After installing CE 126.96.36.199 I wasn't able to suppress the save password check box.
I have tried to follow the IV24300 APAR (see below) instructions without success.
By adding com.ibm.cics.core.ui/canSavePassword=true to a pluginCustomization file for CICS Explorer, the password option is disabled. -pluginCustomization flag in cicsexplorer.ini must be used to specify file location.
Can any one supply cicsexplorer.ini + pluginCustomization files that do the trick?
