I actually experience something of a glitch using MALA 1.04 (just upped to 1.05, but issue persists) on Windows7 32-bit Home Premium. When scrolling through game list, an exception pops up and forces a close. The log it says to check contains the following:
2009/11/06 09:51:12.66 Error: Object Class: TTimer, Object Function: SaveTrackingInformation, Exception Class: Exception, Exception Message: Unable to write to C:\emulation\Utilities\MAME front ends\MALA\selection.ini
When scrolling through a 'favorites' list of ~100 titiles, it doesn't throw the exception as quickly as in the 'all games' list, where it will throw the error within a few seconds. I would have guessed the issue would be permissions, based on the error log entry. I made sure selection.ini file had full control permissions for all users, so not real sure what the deal is...
