I reset the Options to the default. Now I can copy pages but can not copy text in files (Copy Blocks). In the help file (see below) "Also note that this operation is only enabled if the status of the difference is CHANGED" what does this really mean, what would "change"??
---Copy current difference from the second to the first file, keeping the difference in the first file. Note that this operation is disabled after manual modifications to either file. Also note that this operation is only enabled if the status of the difference is CHANGED.---
The quoted Help text applies only to "Add block...", not to "Replace block..." commands, CHANGED status is one of status values for diff blocks, along with DELETED and ADDED (the names should be self-explanatory).
