--- Comment #6 from Simon Kingston simon@kingstonwireless.com --- You are right, xerox.xerox2000x@gmail.com - it does work correctly using the Staging branch of wine (including the email functionality, messaging and calendar; I haven't tried to set up a webcam yet for video calls).
If you want to try to isolate the patch that fixes this (and if that is actually a useful thing to do), I would be happy to verify a few test builds of wine.
I have submitted an application to add LarkSuite to the WineHQ AppDB.
Many thanks for your help, xerox.xerox2000x@gmail.com and gijsvrm@gmail.com
All the best,
Simon
