@delaroca:
maybe not... reading the docs, it seems to me that the TSM fix has to be explicitly enabled and is not involved by default.
However, your suggestion is very useful because the TSM fix is needed for using virtual keyboard with micro$oft office.

Meanwhile, I could change the preferences of virtual_keyboard by opening my virtual mac hd with minivmac instead that basilisk - the config utility doesn't crash with it. It's painfully slow on the tablet, though, and the vga-only resolution of minivmac doesn't help at all, but it can be done if you're patient enough; and doing it on a desktop machine running at some gighertz could make it nicer.
Later, I saw that also the basilisk ii jit which I'm running on my ubuntu box doesn't crash with the virtual keyboard configurator
