Elena,
Thank you for your prompt response.
In fact I tried setting the loading of MMA priority above Gnats Subs, unfortunately the same problem persisted. I considered it could be that I was using 1.56, do you think you were using 1.56 at the time of this incompatibility you experienced. Can you verify, that the problem does not persist now on your machine? If so, can you tell me what version you are using. If there is a fix on my end, to resolve my issue, there is a distinct probability that others as well may have the same problem, identifying this incompatibility on my machine could save others trouble when they are troubleshooting their own issue related to this.
