Why is it taking so long? The cause of the problem, explained above, caused a severe financial problem. These have been bad years to get a bank loan. We have been working our way back to financial health. We are now about at that point.

When will new versions be available? When we know the answer, we will post it here. Please do not e-mail us with this question.


SPECIFIC - These specific messages apply to Lion, Mountain Lion, Mavericks, Yosemite, El Capitan, and Sierra.

NOT work under Lion or any more recent operating system. Your calendar files may be irreparably damaged when you try to Save. (Not always the first time, or even the second -- but eventually you lose all your work.)

InTouch With 3.1.3 will work under Lion through High Sierra depending on the circumstances.
