I have no idea what the error message in my subject header means, but when I tried today to set up LBC (version 1.86.01) on my laptop (IBM ThinkPad T40 running WinXP Pro SP2), I installed it, minimized it to the system tray, and then started to configure it. At one point, I tried to right-click on it to add more nodes in Preferences, and I got an error message box that said "Cannot make a visible window modal." Since I had no idea what the problem was, I decided to reboot and see whether that helped. It did not. I noticed that it had not started with Windows (I suspect I had somehow not checked that option), so I clicked on the destop LBC icon, and I again got the error message. At that point, I decided to uninstall LBC and start again. However, before I do, I'd like to understand what had happened so I don't encounter the same problem again. I should note that I had no trouble installing LBC on my desktop a week or so ago. It's working beautifully. That's why I wanted to put it on my laptop as well.
