I've been quite a bit slack with playing ToMI, so while I've played through episode 1 I haven't even played 2 & 3 yet. So when I wanted to do this today, I've found that both games crash on launch when they're switching to fullscreen mode.
I can run Lair of the Leviathan (or at least get to the settings menu) in windowed mode using the prefs file Will attached here, but for obvious reasons (like anti-aliasing) I'd rather play the game in fullscreen. Well, as soon as I switch to fullscreen in the options menu I get the same crash I previously got directly when launching the game. :(
I'm running Windows 7 x64 RTM here (since we have a MSDN subscription at work and the latest and greates OS used everywhere in the office is still Windows XP).
+++ NEWSFLASH +++
Okay, while I was typing I thought giving Windows' compatiblity options a go before submitting this, and actually setting "Disable visual themes" which makes "regular" Windows apps less, well, new-Windows-Theme-shiny did the trick. But note that this isn't neccessary with Launch of the Screaming Narwhal...
Still, since Windows 7 will be the latest and greatest version of Windows out there in about 11 days you might want to either make that setting the default via the installer (if possible) or look into this crash and fix it for good... ;)
Just my 0.02 EUR... :D
EDIT: P.S., while I'm at it: the link to launch Siege of Spinner Cay in Windows' game explorer actually opens the folder where the game is installed instead of directly launching the launcher as with ToMI 1 & 3...
