"CANNOT PERFORM ...ON A CLOSE DATABASE"

[John Richard Procter]

error when running report "CANNOT PERFORM ...ON A CLOSE DATABASE" after running a long time

Check if another TOPAZ is not still running (maybe the PC crashed).

If you see any errors when starting TOPAZ,
sort them out, it should fix the database error aswell.

Try deleting c:\Tmptopaz.

If it is an older TOPAZ version running, upgrade to the latest one.
