Track Browser looses Setting

[Big Isch]

I've set the track browser to show "Grouping"/"Genre"/"Original Title".

Sometimes, when starting MM, the setting is reset to the initial "Genre"/Artist"/"Album" arrangement.
Then I need to re-assign the "Grouping"/"Genre"/"Original Title" setting. This that lasts for unpredictible
time - sometimes for weeks, sometimes its reset at next start of MM.

I do have no idea, under what circumstances the track browser looses the setting.
I use MM on different PCs with Version 3.2.5-1306, 3.2.4-1304 and 3.2.0-1294 (XP and Vista).

Please help to track-down the problem

Are other settings also lost? Is it lost on all PC's?

All other settings are fine. Problem appears on all PCs.

I tried to find out, when loosing the settings happens, but could not find anything. It appears
randomly since I've started to use the track-browser.
