In the SalesLogix web client (7.5 and 7.5.1) if you have a picklist control that uses a picklist with entries containing commas, the picklist value before the comma is shown, the rest is not visible. Sage has just released a hot fix for this issue along with several other items. This is hot fix 24 for the Sage SalesLogix 7.5.1 web. This hot fix requires 7.5.1 hot fix 6 first.
This hot fix is available from http://support.saleslogix.com or by contacting your business partner.
