TAB stop problem not gone with FM-13.0.2.433

FM-13.0.2.433: I encounter the same problem as it was reported in january. MIF washing did not help.

It happens with all documents which where orginally created with an older FM-version (≤ 12).

It is however not a problem for new documents, into which I have imported ALL formats from the failing one.

1. File > New > Portrait
2. Import all formats from existing file
3. In exiting file select all contens of flow
4. Copy into new file
5. Update the master page usage in new file
6. Close the existing file
7. Save new file with the name of the existing one.
8. Close FM and reopen to check new file.
9. TAB handling OK now

So, Stefan, what the heck is going on here?
