I took a look earlier for the PTSS number but can’t find it? I could have swore I raised it on that system - maybe it was a direct email? I know I also raised it on the usergroups too - just so others could be made aware of it and work around accordingly…
In my tests, I don’t think it was related to a parameter, just a straight forward CASE END (without any OF statements) - I seem to remember 4k leaking??
