Interesting that "STB" has already thought about using .ActivePage.

This looks like one of those projects where extremely tight control of the UI is required. I don't envy you debugging that.

If the issue is with fast typists, maybe keystrokes are being typed while some of this navigation code is executing, causing unexpected results. It might be nice to turn off the keyboard while the code is running, and turn it back on when finished but I don't know how to do that. Something else you might try would be to issue CLEAR TYPEAHEAD, maybe as the first command in the .KeyPress event or the m_JumpToTab method.

One downside to disabling the keyboard or using CLEAR TYPEAHEAD is it can annoy fast typists, as some of their keystrokes will be lost.

One other left-field idea: the guts of the m_JumpToTab method are wrapped in a WITH...ENDWITH which seems unnecessary - I don't see any wrapped code referencing that object. There have been some weird bugs reported with WITH...ENDWITH, if it isn't necessary you could try removing it, or use explicit references instead.
