A project I imported from RH5 (not using the Wizard, never
got that to work) which contains conditional topic tags and
conditional text tags crashes the RoboHelp.exe application when I
try to build with a condition specified. If I turn conditional
builds
offit builds just fine.
I didn't test the empty, hidden column part of this solution,
but removing the merged columns resolved this issue (which fits our
style better anyway).
