Downloaded v5.2 and seeing how it works on my 8330. So far no problems...it works great! No crashing, no piles of blocks at top, no periodic hourglass (memory leak on older versions?), etc.
One suggestion...there is another commercial game named "Tetris" which I had to overwrite to install v5.2. Not that the other game is that good, but it was a 'backup' when BBTetis was acting up.
Thanks for all the hard work you've put in improving BBTetris!
