Not only is this very annoying because I can't take a break and do something else while playing the game. Also I cannot ajust the sound level for the game, [strike]could not find a way to do this in the game and wanted to change it in windows.
Does anyone know how to change the sound settings for Raptor without using the mouse in windows?[/strike]
edit: found the sound setting: it's at the top of the setting screen. I'm so used to having a bar...
Still does anyone know how to keep the Windows moue working while the game is running? (I control the plane with mouse and in the game the mouse does work).

I'm having the same issue. If I alt-tab out of the game, the mouse is disabled. This is COMPLETELY unacceptable behavior in an application. GOG, please fix this!

I haven't had that problem, so it's probably something other than Raptor itself.

never had that problem. in game-options, what have you set as the input?

I have the same problem, though I have the feeling that the mouse is not disabled, but is drawn constantly to the upper left corner of the main desktop. I use Windows 7, this may be an explanation that not everyone has this problem.
I believe the windows standard mouse driver is overwritten with something that is DOS compatible, I had this problem with some emulated games before (but don't ask me which). This is annoying, and I don't know a possibility to reactivate mouse driver, but it is a good possibiliity to remember the shortcuts for your apps =)
