--- Comment #2 from Drude drude@outlook.com --- This might very well be a bug within IMVU itself rather than Wine, the IMVU client and service are both generally pretty buggy on Windows natively and it's an accepted fact by most members who has been using IMVU for any length of time.
IMVU has been suffering higher instability than usual over the last few days, "they must be updating the servers" is the comment most tend to make. I have noticed on Windows that when the service (servers) drops the client, the client often seems to lose stability on the local machine.
The web based client found at [https://secure.imvu.com/next/] has also been having errors along with the desktop and mobile apps, not just for myself but other uses in many locations, not the within the US.
