Hi

I am using version 8.06 and noticed an issue when I try to create a new UDT which has another UDT as a member. The full list of UDT’s are not displayed as shown in the attached image. The list available to me stops at “P” and no scroll bars are available. My workaround so far has been to rename the UDT with a prefix of 1 so it will appear at the top of the list.
