In SPSS 31.0.0.0 (117) running on MS Windows 10 Pro 64-bit, I am frequently encountering a Copy & Paste issue that at least I have never had in previous versions of SPSS (up to version 29 - I skipped version 30):

When copying and pasting text within the same syntax editor window or between different syntax editor windows (I haven't tried with other windows inside SPSS yet), I frequently get the error message 'Unable to paste from the system clipboard. Please try again).' When I then copy and paste the same piece of text again, it usually works.

Even though the following is off topic in this thread, I would like to mention that the well-known bug which interferes with pasting from other applications into SPSS windows and which is discussed in various other threads (e.g., here) has not appeared any more since switching to SPSS 31.

... not for me - I also had to repeat the copy action and then it worked.
