"2 TypeError: aSheet is null"

[Tim Curran]

The error in my subject line appears multiple times each time I switch between views. BlueGriffon otherwise seems to function normally and does not appear to mangle the code in any way. But of course, the error itself is an annoyance. Anyone know what's going on?

(One possible clue: The error only appeared after I activated my license (new computer). The unlicensed version of BlueGriffon did not throw this error, so obviously it's something to do with one of the licensed components.)
