Turbocalc 5 - seems to work perfectly (so far), however:

1) Drop-down menus don't seem to work with a RMB click (or hold).
The 'launch menus' keyboard shortcut does, however, activate the menus.
By default this is RAmiga+Space. To reconfigure, go to Settings>System>iControl>Hotkeys>Menu: Launch menus.

2) Importing Excel files (.xls) does work, however import appears to be limited to Excel 95 versions of files. To import a file into turbocalc saved in Excel 97-2003 (.xls) or Excel 2007+ (.xlsx), it must be saved (using MS Excel) selecting .xls (Excel 95) compatibility from the filetype options.

I'm pretty damn happy to finally get Turbocalc working properly - both of the above issues have taken a while to figure out.
An intuitive (familiar formulas, operators, macros) spreadsheet is a vital tool for me - more so than a .doc comaptible word processor. Also, xls import is a major bonus.

Whimsical aside: Sigh.. I do wish someone with deep pockets would buy out the rights to Digita's Amiga Office software (Wordworth, Turbocalc) - just add .doc/x, .xls/x, (and open equivalents) import/export, and most of the work is done in creating a fantastic office package compatible with all Amiga flavours.

EDIT: Minor details.
