CCS4: RTA sub menu disabled

I have a project using CCS 4.1.3.00038, DSP/BIOS 5.41.07.24, and a C6713 DSP.  The tools->RTA menu is completely grayed out while running and while stopped.  I have RTA enabled in the TCF file (global->enable real time analysis = true).  I searched the community, and found a post suggesting that I turn on RTDX using the JTAG mode.  I tried that, and the menu is still disabled.  The ROV screen comes up fine.

What do I need to do to get the RTA features working?  I was able to get the RTA features working in CCS3.

    An update...

    I did some more searching, and found a reference to using the latest XDC tools as a fix for a similar problem.  I downloaded XDC tools 3.16.05.41 and installed them.  Initially, nothing happened, but it seemed I was still using the 3.10 version that installed with CCS 4.  After fumbling around with CCS V4 settings, I got it to use the 3.16 version.  The documentation on this is pretty skimpy here.  Now when I run my project, the RTA menu is enabled, but the CPU load graph does not update.  I am pretty sure that the idle task has plenty of time to run.  I was getting CPU load plots using the same code under CCS 3.3.

    Some more notes:

    I compared the s62 outputs from the tconf tool.  The differences are that RTDX is enabled, the HST config is changed for RTDX, and interrupt 3 is being used for RTDX_poll.  I saw a note about interrupt 3 and interrupt 9 usage.  Interrupt 3 is enabled in IER, but interrupt 9 is unused and unenabled.

    Alex,

    Sorry about the late response. I believe there is a bug with RTA in CCSv4.1.3. Let me see if I can find a bug report for this.
