During the first minimization, use ⊞ Win+Tab ↹, during the second minimization, use Alt+Tab ↹ and so on.
In the main menu, (before loading a save) use only Alt+Tab ↹. In the case of using Aureal 3D, and closing version notification on startup, don't use Alt+Tab ↹ twice in a row (to come back to the game after closing notification, and later to minimize in the main menu). Don't press on the game icon in taskbar more than once at a row.
Game breaks can still occur though, but less often.
When playing Rayman 2 with the default nGlide settings, it's possible that the game's speed may be running twice as fast than normally intended. To fix this, open the nGlide Configurator and set the refresh rate to 120 Hz or lower, depending on your monitor's refresh rate, instead of the default value.
Add a DEP Exception for Rayman2.exe. Sometimes reboot needed afterwards.
