Thank you for the quick and accurate answer.
From the Changes file, it looks like OneClick is currently at about SVN-465, so SVH-398 must have been a while back.
Any idea when simultaneous use of chat/file transfer and remote control may be back?
Also, if we buy an Single-Site Commercial License today, does it entitle us to all future releases?
The UltraVNC viewer probably won't support it until version 2.0 is released. You're welcome to use the RemoteZilla viewer but there are a lot of features/buttons/menu items that the UltraVNC server doesn't support so they won't do anything but take up toolbar space and the command line options are a bit different.
Updates are always free for OneClick.
