I recently discovered some strange behaviour in two copies of our CRM 2013 deployments and would like to confirm if this problem exists with others?
When we resolve a case we've started to use dates in the Resolution Title and/or description boxes. For instance if we've booked an engineer to attend to a customers call we will enter in the Case Resolution box "Job Booked 25/09/2014".
However I've just started to notice that then the record is redisplayed within the case activities, the dates "/" charters are being rendered with the HTML escape codes / See the attached image.

In the above image both of the case resolutions shown are on the same case. The first one is what happens if you resolve the case "outside" from the case homepage view. The second version is what happened when I opened the case and resolved it from "inside" on the open record.
I can't explain this different behaviour. Knowing I had another version of CRM 2013 (without service pack 1 installed and minus the service module) I tried the same test on those. On that version resolving a case inside or outside caused the HTML escape codes to be rendered in place of the / (forward slash) charter.
Q. Is this a known problem?
Q. Why does one copy of CRM behave differently to another running on the same server?
Q. Is there a fix for this?
Many thanks
Steve
