Hi folks, I recently opened the Syntax window in IBM SPSS 29, and "Active Dataset" is no longer visible. Nor can it be viewed by using View in the Menu option. Any help would be most appreciated.

Thanks, will try this next time it happens.  I found that the following also helped:

Open cmd as admin then type:

reg delete HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs /F

reg delete HKEY_CURRENT_USER\Software\JavaSoft\Prefs /F

Indeed!

It sounds like you're encountering a tricky issue with the Syntax window in SPSS 29. One thing you could try is resetting your SPSS workspace to its default settings, as sometimes layout changes can cause certain elements to disappear. You can typically do this through the "Window" menu by selecting "Reset" or a similar option.

If that doesn't bring back the "Active Dataset" visibility, check if there have been any updates or patches released for SPSS 29 that address this issue, as it might be a known bug.

Hope this helps, and you're back on track soon!
