I tried installing the JiProlog ide, on my Windows 7 laptop, and am missing the JiProlog menu. The right-most menu is the JText menu.
After this happened, I tried installing it on a Windows 7 desktop, and it works fine. The JIProlog menu shows up, and I'm able to open and consult some of the sample PL files, and am able to query some of the predicates. But that menu doesn't show up, in the JIProlog IDE, on my laptop.
Resolved. I was able to get the JiProlog IDE, by running the Jext.bat file directly, from c:\program Files (x86)\JIProlog IDE\bin\Jext.bat
That is, I didn't run the executable Jext.exe, but rather the batch file Jext.bat.
