VAOS 6 General

A: Yes.

A: Printing. Spellchecking.
For a workaround to Printing please see next FAQ for running VA5 and VAOS6 in parallel with the same messagebase. When you set it up like this you can run VA5 on the same messagebase (after you closed VAOS6) and print from it.
For external spell-checkers working with VAOS6 please see the respective FAQ.

A: Let's assume your directory containing the VAOS6 binaries and the messagebase is "P:\VirtualAccess". Create a new directory "P:\VA5" in the same partition. Copy all the VA5 binaries into it (all files from your old VA5 directory ending in *.exe and *.dll). You don't need anything else, no config files, no folders.
Now it's time to tell VA5 where the messagebase is. Create a file "ashmount.ini" in "P:\VA5" with the following content:

[Ashmount]
path=P:\VirtualAccess\

We are done, that's all you need to do.
You can now run the va32.exe in "P:\VA5" like normal and it will use all configuration and messagebase from "P:\VirtualAccess".
I use VA5 this way for printing since VAOS6 cannot print yet.

A: Yes.
Jeff Miller discovered this freeware spell-checker called APSC. It's not supported anymore, but works quite well according to reports.
Mike Blake-Knox recommends FreeSpell based on the Aspell engine which works fine with VAOS.
There is another shareware program which doesn't cost much and looks quite professional, not tested though: Spellcheck Anywhere. It also contains immediate AutoCorrect and a quick Notes application.

And if you are looking for a freeware AutoCorrect software only I can recommend Speed Typing. There's also a commercial version of this program if you need more functionality.

BTW: all the above programs work with virtually any Windows program/text editing area. That's why they work in VAOS as well.

A: Please read the same question in the VA5 General usage FAQ.
