Hi there,

I am having some trouble with my code, and the main problem is that im not sure what the problem is.
I have a fairly standard game -> canvas -> layer manager setup with 2 threads, one for key checking and one for normal movement setup.
The game is tetris by the way. the problem is, it works well until i happen to be holding the down button and completing a line at the same time, i have tried to figure this out but it makes no sense, i have written synchronized in all the right places (i think) and everything like that but it still does some pretty weird stuff.

If anyone would like to look at this i would greatly appreciate it, someone with more of an understanding of threads would be awesome. and maybe even a little reward for an explaination.

the code for my game is at

Sweet, Thanks

The issues are not immediately apparent, but the overall game design makes sense except for where is your main() ?
