I´m sure, there is no limitation, even DB 1.xx had none (my project had >5000 lines, primary because I did not optimized a lot of the code, which I do now in the new verion). Probaly there is somethink different that causes the problem.
Look, my project locks up at start if I use Patch 2, and I was not able to find the reason, but then I found out that the memory allocation was messed up, so all my array initializations at the start caused a lockup.
