Is it just me, or is anyone else having trouble with saved games using v1.9?

I was messing around in ms pacman maze madness, got quite far, so turned off after it had saved my game. I was a tad worried that turning it off would stop my game from being saved properly, so I turned back on, backed up my save to the .sav file, loaded ms pacman from the menu and checked my progress. All was fine, my game had been saved. I turned off,  and played something else.

When I came back to load my ms pacman game again, my progress had been wiped.

This is getting to be a habit now - lots of games lose their saves even though they worked fine previously.

Any thoughts?
